This variable gain amplifier is controlled by a single 0V to 3.3V positive supply voltage. The RFVA1027 is packaged in a small 7mm x 7mm leadless laminate MCM which contains solid thermal vias for ultra low thermal resistance. This module is internally matched to 50 and is easy to use with no external matching components required.
