As the adoption of 5G—the latest generation of cellular communications—gains momentum, the race is on to push out 5G communications infrastructure. Cellular operators are busy deploying infrastructure and have already commenced their marketing initiatives to entice us to upgrade our smartphone contracts and handsets so we can benefit from the significantly improved data rates. Unlike the previous generation change from 3G to 4G, the communications architecture of 5G is not an iterative upgrade. 5G encompasses first-time frequencies in the 24GHz to 40GHz millimeter wave (mmWave) spectrum in addition to coexisting with multi-radio communication networks in the licensed and unlicensed sub-6GHz bands.
Achieving 5G’s significantly higher data rates, which are forecasted to be a minimum of four times faster than 4G requires the high-bandwidth mmWave spectrum. However, using these much higher frequencies introduces some technical and operational challenges designers must address. A key consideration is that the maximum possible range a signal can send decreases as the frequency increases due to higher propagation losses. This is one of the reasons why a mmWave 5G deployment requires many more base stations than that of 4G. Making 5G mmWave commercially viable using an optimal number of mmWave base stations at the same time as ensuring that mobile handsets receive a sufficiently strong signal led RF engineers to implement beamforming of the mmWave signals. When it comes to designing the massive multiple-in multiple-out (MIMO) antennas, the higher frequency means the transmit/receive elements are much smaller than 4G, enabling the multiple mmWave antenna elements required for a beamforming array to be physically small. Beamforming, also termed beam steering, uses a combination of analog phase shifters and digital control techniques to dynamically concentrate output power into a single lobe to achieve the maximum signal-to-noise ratio and bit error rates for any one signal path.
When it comes to the design of the infrastructure equipment, one of the aspects of mmWave RF development is that for frequencies in the order of 30GHz and above the materials used for a product’s PCB substrate can introduce signal losses and unwanted propagation influences. Ideally, the substrate’s dielectric constant (Dk) needs to be low. This led the industry to adopt thinner PCB sizes and different substrate materials, such as polytetrafluoroethylene (PTFE) laminate. Making a coaxial connection between a stripline board and an antenna has traditionally used solderless compression-type connectors. However, as frequencies go higher and the substrates become thinner and softer, the compressive force on the PCB can compact the substrate, producing a capacitive effect that can cause reflections—which in turn negatively impacts the Voltage Standing Wave Ratio (VSWR)—resulting in lower link performance and decreased transmitter efficiencies.
Rather than using a solid mating connector surface, the Amphenol SV Microwave LiteTouch series of solderless PCB connectors use a rounded bead-contact spring pin assembly to minimize the transmission of mating torques to the main assembly (Figure 1).
Figure 1: On the left is a traditional solderless compressive force connector showing the deflection of the PCB substrate. On the right is the solderless Amphenol SV Microwave LiteTouch connector, which exerts no deflection or compressive forces on the PCB assembly. (Source: Amphenol SV Microwave)
The screw-mounted LiteTouch series is designed for 2.92mm, 2.4mm, and 1.85mm connectors. An SMA version is available too. Designed for 50Ω impedance, the 2.92mm connector is rated up to 40GHz, the 2.4mm up to 50GHz, and the 1.85mm to a maximum frequency of 67GHz. The SMA connector is suitable for use up to 26.5GHz. In addition to the board-mounted version, a PCB edge launch series is available too.
Figure 2 illustrates the impact on VSWR reflections using a standard compressive connector can have above 30GHz—see the red trace. By comparison, the blue plot shows a minimal increase in reflections when using an Amphenol SV Microwave LiteTouch connector.

In addition to use in 5G infrastructure equipment such as antennas, front-end modules, and beamformers, designers can use the Amphenol SV Microwave LiteTouch connector series, a variety of RF and high-speed digital test and measurement equipment, RF pallets, and development and prototyping boards.

The registered connector, better known as the RJ connector and commonly known as a modular connector, is one of the most frequently used connectors, present in almost every business and household in America. Yet, it is also one of the most misunderstood, and frequently plagues its users with doubts as to whether they are using the correct connector for their application.
Before I try to shed some light into the RJ series connector and the vast number of variations that encompass the series, let me first say that the RJ connector has been the de facto connector for the telecommunication industry for a number of decades. It has been the “work horse” when it comes to electronic applications that require the transmitting and receiving of data. For instance, in the Information Technology (IT) world, these connectors can be abundantly found attached to every server, in every server room throughout corporate America. They’re also attached to every LAN terminal, copier, fax, and wireless access point. In homes, they connect phone landlines, and bring the internet to the masses via, modems, routers and computers. When you think twisted pair cabling you intuitively also assume the use of RJ connectors for the termination. The combination of these non-mutually exclusive parts, connector and twisted pair wire, deliver the overall capacity of the interconnect that will meet any specification.
Many new connector types have recently made their way into the marketplace, more specifically into the consumer market. For instance, USB and HDMI, both very good connectors, but in my opinion both have little chance of displacing the RJ connector anytime soon. The main reasons for this are multiple. First, the small form factor makes them ideal for IT applications. Second, cost and availability of these connectors. You can buy a handful of these connectors and find them at just about any hardware supplier for under a $1 each. And lastly, the ability to terminate these connectors with ease. Not to mention the acceptance by OEMs as the standard connector for IT applications. Fast and easy termination of these connectors makes them ideal for new installations and field service repairs.
Figure 1: Typical server connections
The following information is by no means exhaustive, but it does provide a short list to get you started on selecting the right connector for the job.
So why is there so much confusion figuring out what connector to use for your application or what connector you have? Perhaps is because over time the RJ connector has evolved to meet the demands for greater and faster through puts of data. Some of these changes have only required more pins to be added to existing versions of the connector while other changes have increased the number of physical pins the connector houses. In both cases, the connectors themselves look very similar to each other while their actual specifications could be drastically different.
I’ll try to demystify the RJ connector starting with some basic information and examples of common industry abbreviations and acronyms. Note that some of these don’t only apply to the connector but also to the wire that is used with these connectors. The more you know about the connector-wire combination the better off you’ll be at understand what connector you’ll need for your application.
Most of the time, you will find these acronyms and suffixes attached to the connector part number or description.
Table 1: RJ connector nomenclatures
Many of the basic names have suffixes that indicate subtypes:
• C: flush-mount or surface mount
• F: flex-mount
• W: wall-mount
• L: lamp-mount
• S: single-line
• M: multi-line
• X: complex jack
List 1: https://en.wikipedia.org/wiki/Registered_jack
Acronyms for twisted wire:
Table 2: https://en.wikipedia.org/wiki/Twisted_pair
Figure 2: https://en.wikipedia.org/wiki/Twisted_pair
Table 3: https://en.wikipedia.org/wiki/Category_5_cable
Table 4: https://en.wikipedia.org/wiki/Twisted_pair
I hope you have found this handy information on RJ connectors useful and as previously stated, there is much more to these connectors that I’ve omitted, including various standards and certifications, recommended wire runs lengths, recommended bend radius, etc. For standard landline phone service, RJ 11 connectors would be fine. For most residential audio video and data applications, Cat.5 UTP wire with RJ45 connectors is probably the standard. More demanding commercial applications, CAT.5e or better would probably fit the ticket with special consideration to cable shielding, cable stranding, plenum approved or not and possibly the cable jacket insulation material.

Designers often use high reliability, often shortened in conversation to “Hi-Rel," to describe products that are designed to deliver excellent performance in demanding, mission-critical applications. Hi-Rel is often another way of describing military and aerospace products. It is sometimes assumed that products approved to a military standard are naturally superior to other products that are not. However, it may be time to stop thinking of high reliability and start talking about appropriate reliability.
One of the most essential characteristics of any connector is defining the number of mating cycles. A mating cycle is the act of mating and un-mating a connector once. Most manufacturers publish a minimum mating cycle count in their specifications, as it indicates how long a connector will last. Connecting and reconnecting will have a physical effect on the electrical contacts, which, in turn, will affect their electrical performance.
The goal of every connector manufacturer is to keep the contact resistance—the extent to which the connector contacts hinder the flow of an electric current—to a minimum. Testing a connector for its number of mating cycles measures its contact resistance.
A military specification connector—the archetypal Hi-Rel solution—might have a published performance of 500 or even 1000 mating cycles. But this is not the high point of the connector industry. The humble USB connector that has been with us for nearly three decades is designed to provide up to 5000 mating cycles, and there are even versions available that will provide a service life of 20,000 mating cycles or more.
There will always be the need to choose Hi-Rel connectors for specific designs. Connector performance is not purely governed by mating cycles; the environment in which the connector will be used must also be considered. We regularly discuss IP ratings, shock and vibration, and resistance to electromagnetic interference (EMI). The need to meet some or even all of these conditions will have an enormous effect on the design of any connector.
However, assuming that a connector with a MIL part number is the only way to obtain this performance is wrong. Almost all manufacturers who make products conforming to a MIL standard also make the same connector under their part number. These are usually made on the same production line, using the same materials, and delivering the same performance. For example, the ever-popular D38999 Series III circular connector is available from Amphenol as the TV, Souriau as the 8D, and ITT Cannon as the KJA families.
The difference will be in detail. A MIL-DTL part number might be subject to additional inspection or be supplied with a spare contact and removal tool. However, unless these are vital for your design, choosing the manufacturer's part number could significantly reduce costs. The same is true for D-Sub connectors sold as M24308 and micro-D connectors as M83513 (Figure 1). Find out what the manufacturer calls their equivalent product and get ready to save money.
Figure 1: Amphenol Pcd M2000 D-Sub Connectors are military-qualified and meet MIL-DTL-24308 requirements. (Source: Mouser Electronics)
Another vital thing to remember is that connectors do not have to be designed to a military specification to be capable of military-grade performance. Swiss manufacturer LEMO has been making connectors for 80 years using their innovative push-pull locking system, which provides superior ease of use and reliability. Many of their connectors have been subjected to a range of military tests which prove their performance in certain applications, the most aggressive of which are the gunfire vibration standards. Meeting these standards for shock and vibration makes them suitable for a wide range of uses. LEMO connectors such as the M Series have proven time and again their suitability for use in tough conditions such as the motorsport industry (Figure 2).

Other connector manufacturers go above and beyond published standards to provide their customers peace of mind. An excellent example is US manufacturer Samtec which developed the Severe Environment Testing program. Samtec understands that the growth of high-speed electronics into almost every industry segment will expose standard commercial connectors to harsh conditions. The SET program takes traditional families of connectors such as the SEARAY™ and mPower™ and subjects them to a battery of tests that goes far beyond the standards of “commercial” products. In this way, designers are provided with cutting-edge board-to-board connectors that can withstand the rigors of demanding applications.
High-reliability connectors represent the gold standard of the interconnection industry. Designed to work in applications where failure is not an option, they provide the superior performance and reliability vital to many designs. But this comes with a price.
The next time you need a solution for a demanding requirement, ask whether a high-reliability connector is needed at all. The connector industry is enormous and diverse, and a little time spent understanding how a particular product will perform could save you a lot of money in the future.
The world is changing. You can see it on the roads, in buildings, and in cities.
Meeting that change is a new family of highly accurate, single-chip millimeter-wave (mmWave) sensors enabling applications ranging from automotive radar to industrial automation. These precision sensors give designers a platform to bring new levels of intelligence, safety, and autonomy to automobiles, buildings, factories, and drones. Advances in technologies such as mmWave sensors are timely. For example:
These changes will require new levels of precise sensing to detect the range, velocity, and angle of objects; to penetrate plastic, drywall, glass, and other materials; and to perform in extreme and challenging environmental conditions such as rain, fog, dust, light, and darkness.
Until now, sensing systems have used discrete components to transmit, receive, and analyze signals. Using discrete components on circuit boards increases the size, power and overall cost of systems. Our technology—built on a complementary metal-oxide semiconductor (CMOS) platform—integrates a best-in-class digital signal processor (DSP) and microcontroller (MCU) into a single, small package that will use less power while delivering up to three times more accuracy than current solutions.
Sensors in automotive applications will support advanced driver assistance systems (ADAS) designed to help warn, brake, monitor, and steer our cars as we drive to the grocery store, to work, and on long road trips across the country. These increasingly in-demand systems are essentially the first step on the technology road toward full autonomous driving.
Technologies widely available in cars today include adaptive cruise control, automatic emergency braking, blind-spot warning, lane-departure warning, and even parking assistance. But future advances—autonomous parking, highly automated driving and, ultimately, hands-off-the-wheel autonomous driving—will depend on increasingly sophisticated sensing intelligence from radar, as well as from technologies such as laser, ultrasonic, infrared, and lidar.
These sensors are enabling the next level of efficiency and intelligence for buildings and factories.
The applications for industrial systems are myriad. For example, the sensors’ unprecedented accuracy will enable companies to precisely measure the fluid levels in tanks as a way to manage inventory and detect leaks early. Perimeter sensors will provide security systems with precise motion-sensitive detection and tracking. Traffic-monitoring systems enabled with mmWave sensors will create smarter cities through reduced traffic stress.
Sensors also will provide more precision for robots and forklifts and be able to determine how many people are in a room.
Our world is in the midst the next great industrial revolution that will require unprecedented precision. Technologies such as mmWave will enable designers to meet these needs in new, innovative ways.

More than ever, manufacturers rely on their reputation with users and consumers. The competitive marketplace, combined with the customer’s appetite for innovation in even the most everyday appliances, has placed increased pressure on manufacturers to find solutions that improve the quality of their product range.
Manufacturers choose components that deliver the reliability and performance needed to provide customer satisfaction. However, manufacturers also understand even high-quality components cannot prevent failures if they are incorrectly assembled.
This means designers are constantly investigating ways to make the production process as efficient and consistent as possible. In the pursuit of error-free manufacturing, products need to be designed with the assembly process in mind, and this is especially true when looking at the role of connectors in modern electronics.
A mismatched connector will cause a failure, the consequences of which range from an inconvenient warranty claim to a potentially life-threatening accident. To prevent these problems, engineers must take steps to ensure safe and reliable operation at the earliest stages of the design.
One of the often overlooked aspects of a connector is the extent to which they depend on manual assembly. Even in today’s highly automated world, the termination of power, data, and signal connectors relies on skilled operators. And for the high-volume environments found on production lines, choosing the right connector can deliver measurable benefits in reducing failure rates and increasing efficiency.
Whether connectors are designed with oversized terminals to carry high currents or equipped with high circuit counts for the latest data applications, considerable force can sometimes be required to operate them. These forces pose risks for operators as high mating and unmating forces can result in fatigue. This can lead to errors such as improper alignment of connectors, damage to contacts, and even repetitive strain injuries for operators.
With health and safety paramount for manufacturers and operators, connectors that deliver a low mating force reduce operator fatigue and consequently improve productivity and accuracy. These types of connectors should feature innovative contact designs like the Molex Fit Family of board-to-wire connectors (Figure 1). Power delivery and distribution in the Molex Fit Family connectors is achieved using a receptacle terminal with six points-of-contact to deliver the best possible electrical performance while minimizing the force required to mate and unmate.
Figure 1: Molex Fit Family Connectors can be modified, customized, or adapted to meet virtually any application needed. (Source: Mouser Electronics)
Connectors can also be designed with physical features that prevent incorrect alignment. The Molex color- and mechanically keyed connectors are designed with asymmetrical insulators that prevent them from being mated unless in the correct orientation. This reduces the number of errors during assembly and ensures the final product is working correctly before delivery.
However, mechanical keying alone cannot prevent errors when assembling complex equipment requiring multiple connectors. In applications that use several similar connectors, it is possible for fatigue to cause errors, as a moment of inattention can result in a cable being connected to the incorrect location, with potentially disastrous results.
To provide a highly visible solution for hard-working operators, the Molex connectors are manufactured in a range of different colors. By matching color-keyed plugs with the correct receptacles, users are given an instant indication that all components have been assembled correctly. Combined with mechanical keying, this positive feedback reduces the chance of errors and delivers confidence during quality control.
Consumer appliances are exposed to surprisingly extreme conditions within the home. The dangers of high humidity, harsh chemicals, extreme temperatures, and vibration in home appliances could quickly destroy sensitive electronics. To protect delicate printed circuit boards (PCBs), many manufacturers turn to potting as a solution. This process encapsulates the completed PCB within a compound that hardens the seal and protects the PCB against moisture and dust while also remaining flexible enough to respond to expansion caused by temperature changes. In addition to protection against contaminants, the sealing compound provides mechanical support for solder joints on PCB-mounted components.
Connectors intended for mounting onto a potted PCB need to be designed so the compound cannot interfere with the mating process. Molex manufactures a range of solutions without drain holes that are compatible with the potting process. The Fit family of connectors, along with the Micro-Lock and Spot-On connector ranges, can all be used in these applications to deliver additional stability and greater protection.
The best connector in the world is only as reliable as the process used to assemble it. With increased demand across the electronics industry for higher current ratings, higher circuit counts, and greater compactness, the design of connectors must evolve to ensure greater reliability during assembly and operation.
Molex manufactures a range of connectors specifically designed to address quality and performance issues by reducing the number of errors associated with improper installation. With low mating forces, a range of options like color- and mechanical keying, and a selection of potted solutions, Molex connectors deliver confidence for users and manufacturers.

In recent years, the design of high-quality RF/microwave systems has experienced a significant transformation thanks to four pivotal advancements:
At the forefront of these cutting-edge RF/microwave connectors are the VITA OpenVPX-specified devices, which have proven to be invaluable across a wide range of military and industrial applications, paving the way for more efficient and innovative communication systems.
The important Sensor Open Systems Architecture (SOSA) standard leverages the OpenVPX standard to define card profiles with specifications for features such as pinouts, networking capabilities, and serial interfaces. The SOSA Reference Architecture is specifically intended to support US DoD Command, Control, Communications, Computer, Intelligence, Surveillance, Reconnaissance, and Tracking (C4ISRT) systems development, but is very useful in many applications.
The VPX (VITA 46) specification was ratified in 2007 as the next-generation VME backplane. Then, in 2009, VITA introduced OpenVPX (VITA 65) to address interoperability issues. This brought profiles so that one manufacturer’s boards would always talk to another’s in a designated backplane/chassis setup. OpenVPX defined different "planes" in the specification (control, data, expansion, management, and utility planes) that grouped other signals/functions. Then, it defined the signal types in “pipe” classes, which include ultra-thin pipe (x1), thin pipe (x2), fat pipe (x4), and double fat pipe (x8) as the principal groups, as well as a couple of others.
SOSA requirements for 3U and 6U modules refer extensively to the VITA VPX standards. However, SOSA restricts good VPX primary slot profiles to a relatively small set of three 6U and six 3U profiles.
Meanwhile, the full VITA 65 OpenVPX standard provides dozens of 6U VPX and 3U VPX slot profiles with user-defined pins and, therefore, systems with unique backplanes designed to be used with specific modules. SOSA limits this individuality.
The SOSA standard also recognizes the need for excellent cooling methods so that power growth can be accommodated to support future processing needs. SOSA has defined a 1.00” slot pitch for conduction and liquid cooled modules to accommodate various cooling methods and a 1.5" pitch for air flow through modules.
While the SOSA approach establishes guidelines for military applications in command & control, communications, computers, cyber warfare, intelligence, surveillance, and reconnaissance (C5ISR), many civilian/commercial systems applications can benefit from this design philosophy. Aircraft and railroad control designs are sure-fire users, and factory industrial control systems will also help.
First, let's take a look at the four S’s of microwave connectors:
Figure 1: An SMPM vertical PC board mount connector for a single cable connection with a frequency range of DC to 65GHz. (Source: Mouser Electronics)
The most compact connector series requires less than 2mm x 2mm of PCB real estate. Larger connector types are meant to support high-power needs, such as the 5G wireless infrastructure. As an example, the sizes of quad coaxial modules for a backplane vary from the SMP module at 0.890" wide to the SMPM at 0.668" and the SMPS at 0.470” (Figure 2).
Figure 2: RF/coaxial SMPM and SMPS multiport PCB connectors often come in dual and quad configurations and enable extremely high frequencies of DC up to 100GHz. (Source: Mouser Electronics)
Table 1 shows the basic specifications of SM-series miniature 50W plug-in RF coaxial connectors.
Table 1: The basic specifications of SM-series miniature 50W plug-in RF coaxial connectors. (Source: Mouser Electronics)
All three connectors offer a Voltage Standing Wave Ratio (VSWR) (2MHz to 40GHz) of 1.5:1 maximum and insertion loss of 0.12 (as seen in Table 1). They are rated for -65°C to +165°C operation and allow radial misalignment of up to 3°, and axial misalignment of .010” maximum.
For example, the Amphenol VITA 67 coaxial interconnects offer a robust, rugged, high-speed cabled solution (Figure 3). Two specifications are available: VITA 67.1 with 3U, 4-port SMPM configuration and VITA 67.2 with 6U, 8-port SMPM configuration. The floating SMPM coaxial contacts ensure excellent RF performance in any mating condition.

These parts are also designed for side-by-side implementation with VITA 46 high-speed data connector hardware (Figure 4) and can be connected to .086" and smaller diameter coaxial cable types (Figure 5). The design engineer can also choose a direct-to-PCB configuration—instead of a cabled.

Figure 5: Coaxial plug-in modules are available in several sizes. (Source: Mouser Electronics)
Advancements in RF/microwave systems have been made more accessible due to crucial developments such as RFICs/MMICs, improved EDA software, advanced antenna availability, and superior RF/microwave and data connectors. The VITA OpenVPX-specified devices and SOSA architecture play a vital role in providing standardized solutions for military, industrial, and civilian applications. The SOSA standard offers excellent cooling methods and promotes interoperability, ensuring future-proof and efficient designs. The range of microwave connectors, including SMP, SMPM, and SMPS, offers varied capabilities to cater to diverse application requirements.
As the demand for quality RF/microwave connections continues to rise in military, SATcom, and 5G/6G wireless applications, companies like Amphenol are providing a wide range of reliable and high-performance products. These innovative developments have the potential to significantly impact various industries, including IoT, satellite, networking, aerospace, aircraft and train control, and telecommunications.
Jim Harrison is an electronics engineer and has held senior design engineering positions with industrial automation and scientific instrumentation companies since 1989.

We all understand connectors are an integral part of heavy equipment used in the harshest environments or in heavy-duty off-road applications.
Chances are we've taken their importance for granted—they're unsung, but connectors can be one of the first items put to test and, of course, must be strong and reliable. Over the course of use, these connectors might be coated in grime or caustic materials and exposed to extreme heat or cold operating temperature ranges (-55°C to +125°C).
Yet, these connectors are tasked with doing a vital job—routing electrical signals and maintaining a positive connection at all costs. Obviously, design engineers need the most reliable connectors for their projects.
In this week's New Tech Tuesdays, we'll look at the Amphenol Sine’s DuraMate™ family of connectors and their applications.
Amphenol Sine Systems’ DuraMate™ family features heavy-duty plastic (AHDP) and metal (AHDM) multi-pin circular connectors with a 3 key-way quick-connect, bayonet locking system manufactured to withstand the complexities and challenges of harsh environment off-road applications. The low insertion force stamped & formed or machined terminals offer improved manufacturing efficiencies and standard WTA (Wide Thread Adapter) provides maximum access to rear grommet and improved serviceability. When in the mated condition, the connectors are vibration resistant and compliant with IP69K protection from dust, water, mud, and other contaminants. A high-temperature silicone seal provides an additional barrier from lubricating oils, hydraulic fluids, and fossil fuels. The water-resistant connectors are ideal for commercial and heavy-duty off-road vehicles, agriculture, construction, and marine applications.
The connectors' backshells, the mechanical device threaded into the rear of an electrical connector, offer standard or compression-fit design to resist maximum pull-out forces and facilitate strain-relief for jacketed cable ranges. The backshells are available in several options (Figure 1). Some backshell options allow for moisture evaporation or weep holes. Accessories include protective caps, additional lock washers, panel nuts, and rubber flange seals.
