    Qorvo's RFDA0057 is a dual-channel, digital controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less than 7dB in its maximum gain state. The gains of two 6-bit digital step attenuators are programmed with a serial mode control interface (SPI). The RFDA0057 is packaged in a small 7mm x 7mm 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.
