The gains of two 6-bit digital step attenuators are programmed with a serial mode control interface (SPI). The RFDA0047 is packaged in a small 7.0mm x 7.0mm leadless laminate MCM, which contains plated through thermal vias for ultra-low thermal resistance. This module is easy to use with no external matching components required.
