2.4 GHz ZigBee®/Smart Energy Front-end Module

The SKY66109-11 is a high-performance, fully integrated RF Front-End Module (FEM) designed for ZigBee®/Smart Energy applications.

The SKY66109-11 is designed for ease of use and maximum flexibility. The device provides integrated and fully matched input baluns, an integrated interstage matching and harmonic filter, and digital controls compatible with 1.6 to 3.6 V CMOS levels.

The RF blocks operate over a wide supply voltage range from 2.0 V to 3.6 V that allows the SKY66109-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve.

The SKY66109-11 is provided in a small, 20-pin, 3 x 4 mm Multi- Chip Module (MCM) package.
