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