RFDA0026

DIGITAL CONTROLLED VARIABLE GAIN AMPLIFIER

700MHz TO 1035MHz, 6-BIT 0.5dB LSB CONTROL

RFMD's RFDA0026 is a digital controlled variable gain amplifier featuring

high linearity over the entire gain control range with noise figure less than

4.1dB in its maximum gain state. The gain of the 6-bit digital step attenua-

tor is programmed with a serial mode control interface (SPI). The

RFDA0026 is packaged in a small 6.0mmx6.0mm leadless laminate

MCM, which contains plated through thermal vias for ultra low thermal

resistance. This module is easy to use with no external matching compo-

nents required.
