详细描述
RFMD’s RDA2032Z is a digital controlled variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. The attenuation of the 6-bit digital step attenuator is programmed with a parallel mode control interface. The RDA2032Z has two amplifier stages packaged in a small 5.2mm x 5.2mm leadless laminate MCM containing plated through thermal vias for ultra low thermal resistance. The footprint for this module is directly compatible with a 5mm x 5mm 32-pin QFN. This module is easy to use with no external matching components required.
