ADL6316 Transmit Variable Gain Amplifier (VGA)

Analog Devices ADL6316 Transmit Variable Gain Amplifier (VGA) provides an interface from radio frequency digital-to-analogue converters (RF DACs), transceivers, and systems-on-a-chip (SoC) to power amplifiers. Integrated balun and hybrid couplers allow high-performance RF capability in the frequency range of 500MHz to 1000MHz. To optimise performance vs. power level, the ADL6316 includes a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA). All of the devices integrated into the ADL6316 are programmable via a 4-wire serial port interface (SPI). The ADL6316 is manufactured in an advanced silicon-germanium (SiGe), bipolar complementary metal-oxide semiconductor (BiCMOS) process.
