Product Description
RFMD’s RFDA0057 is a dual-channel, digital controlled variable gain amplifier fea-
turing 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. This module is easy to use with no
external matching components required.
