Product Description
RFMD’s RFDA2125 is a digital controlled variable gain amplifier for
broadband applications with external matching to allow for
configurations in different bands with a single module. It features
exceptional linearity 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 RFDA2125 is packaged in
a small 5.2mm x 5.2mm leadless laminate MCM, which contains plated
through thermal vias for ultra-low thermal resistance.
