Mini-Circuits RCDAT-18G-63 Programmable Attenuator
Mini-Circuits RCDAT-18G-63 Programmable Attenuator is suitable for a broad range of signal level control applications from 100MHz to 18GHz and provides 0 to 63dB attenuation in 0.25dB steps. This general-purpose, single-channel device features a unique design that maintains linear attenuation change per dB, even at the highest attenuation settings. The RCDAT-18G-63 is housed in a compact, rugged package with 2.92mm female RF connectors and three ports: USB Type-C®, Ethernet (RJ45), and 15-pin D-sub control. The DC supply can be connected via the USB or D-sub ports. This programmable attenuator can be controlled through USB, Ethernet, RS232, or TTL (via a D-sub connector). Full software support is provided by Mini-Circuits. Typical applications include satellite communications, receiver sensitivity testing, and military.
