RFDA0066

DIGITAL CONTROLLED VARIABLE GAIN AMPLIFIER

5MHz TO 1GHz, 12-BIT 0.5dB LSB CONTROL

RFMD's RFDA0066 is a digital controlled variable gain amplifier featuring

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

3.5dB in its maximum gain state. The gain of dual 6-bit digital step attenu-

ator is programmed with a 12-bit Serial Peripheral Interface (SPI). The

RFDA0066 is packaged in a small 6.0mm x 6.0mm leadless laminate

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

resistance. The module is easy to use with a few external DC blocks and

RF chokes.
