Product Description
RFMD's RFDA3016 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less than 5.0dB in its maximum gain state. The gain of the 6-bit digital step attenuator is programmed with a
serial mode control interface (SPI). The RFDA3016 is packaged 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.
