Product Description
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
5.2mmx5.2mm leadless laminate MCM with plated through thermal vias for low
thermal resistance. The amplifiers’ bias chokes and DC blocks are external allowing
for optimum performance over specific bands within 10MHz to 850MHz.
