The ADL6346B is a transmit two-stage differential amplifier that provides an interface from RF digital-to-analog converters (DACs), RF transceivers, and systems on a chip (SoC) to power amplifiers. The ADL6346B also includes an integrated impedance matching and an integrated RF balun so that it can be configured as a differential input, single-ended output to allow high-performance RF capabilities in desired frequency ranges.

To optimize performance vs. power level, the ADL6346B includes the ability to adjust the DC operating and linearization currents using external resistors.

The ADL6346B is manufactured on an advanced silicon germanium (SiGe), bipolar complementary metal-oxide semiconductor (BiCMOS) process.
