RFDA0025 Digital Controlled Variable Gain Amplifier

RFMD’s RFDA0025 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range. The 6-bit digital step attenuator is programmed with a serial mode control interface. The RFDA0025 is packaged in a small 5.2mm x 5.2mm 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 5mm x 5mm QFNs. The amplifier’s bias choke and DC blocks are external, allowing for optimum performance over specific bands within 50MHz to 850MHz.
