Product Description
RFMD’s RFDA2077 is a dual channel digital controlled variable gain amplifier fea-
turing high linearity over the entire gain control range with noise figure less than
6.5dB in its maximum gain state. The gains of two 6 bit digital step attenuators are
programmed with a serial mode control interface (SPI). The RFDA2077 is packaged
in a small 7.0mmX7.0mm 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.
