Product Description
RFMD's RFDA0056 is a digital controlled variable gain amplifier featuring high lin-
earity over the entire gain control range. The gain of the 6-bit digital step attenuator
is programmed with a serial mode control interface (SPI). The RFDA0056 is pack-
aged in a small 6.0mm x 6.0mm 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.
