RFMD’s RFDA0025 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 with a serial mode control interface. The RFDA0025 is packaged in a
small 5.2mmx5.2mm leadless laminate MCM with plated through thermal vias for
ultra low thermal resistance. The footprint for this module is directly compatible
with most 32-pin 5mmx5mm QFNs. The amplifier’s bias choke and DC blocks are
external, allowing for optimum performance over specific bands within 50MHz to
850MHz.
