GENERAL DESCRIPTION

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.
