The ADL6337 belongs to a family of transmit variable gain amplifiers (VGAs). It provides an interface from RF digital-to-analog converters (DACs), transceivers, and systems on a chip (SoC) to power amplifiers. It also includes an integrated RF balun and can be configured as a differential input, single-ended output to allow high-performance RF capability in the 500 MHz to 5200 MHz frequency range.
