General Description

RFMD’s RFDA0057 is a dual-channel, digital controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less than 7dB in its maximum gain state.

The gains of two 6-bit digital step attenuators are programmed with a serial mode control interface (SPI).

The RFDA0057 is packaged in a small 7.0mm x 7.0mm leadless laminate MCM, which contains plated through thermal vias for ultra-low thermal resistance.
