The ADL6317 is a transmit variable gain amplifier (VGA) that provides an interface from radio frequency digital-to-analog 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 1500 MHz to 3000 MHz.

To optimize performance vs. power level, the ADL6317 includes a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA). All of the devices integrated into the ADL6317 are programmable via a 4-wire serial port interface (SPI).

The ADL6317 is manufactured on an advanced silicon germanium (SiGe), bipolar complementary metal oxide semiconductor (BiCMOS) process.
