Product Description
RFMD’s RFDA0016 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range. The 6-bit digital step attenuator is programmed via a serial mode control interface. The RFDA0016 is packaged in a 6mmx6mm leadless laminate MCM with plated through thermal vias for low thermal resistance. The amplifier’s bias chokes and DC blocks are external allowing for optimum performance over specific bands within 50MHz to 1000MHz.
