RFDA2077

DIGITAL CONTROLLED VARIABLE GAIN

AMPLIFIER 1700MHz to 2400MHz

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.
