详细描述
RFMD's RFDA0045 is a digital controlled variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. The 6-bit digital step attenuator is programmed with serial mode control interface. The RFDA0045 is packaged in a 5.2mm x 5.2mm 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 10MHz to 850MHz.
