The SKY66109-11 is a RF Front-End Module (FEM) for ZigBee® and Smart Energy applications. It consists of an integrated PA, LNA with a programmable bypass, integrated antenna switching and transmit and receive diversity function, fully matched input baluns, an integrated interstage matching and harmonic filter, and digital controls compatible with 1.6 to 3.6 V CMOS levels. This FEM requires a supply from 2 to 3.6 V enabling it to work with battery powered applications. It is available in a 20-pin MCM package that measures 3 x 4 x 0.9 mm.
