Product Description
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.
