Product Description
RFMD’s RFDA2015 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 parallel mode control interface. The
RFDA2015 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 output amplifier is externally matched, allowing for
optimum performance over specific bands within 500MHz to 2500MHz.
