Product Description
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.
