Product Details

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.

To optimize performance vs. power level, the ADL6337 includes high linearity amplifiers and a digital step attenuator (DSA). All of the ADL6337 components are programmable via a 3- or 4-wire serial port interface (SPI).

The ADL6337 is manufactured on an advanced silicon germanium (SiGe), bipolar complementary metal-oxide semiconductor (BiCMOS) process.
