The SKY66108-11 is a high-performance, fully integrated RF Front-
End Module (FEM) that is designed for ZigBee®/Smart Energy
applications.
The SKY66108-11 is designed for ease of use and maximum
flexibility, with integrated fully matched input balun, integrated
inter-stage matching and harmonic filter, and digital controls that
are compatible with 1.6 V to 3.6 V Complementary Metal Oxide
Semiconductor (CMOS) levels.
The RF blocks operate over a wide supply voltage range from
2.0 V to 3.6V, which allows the SKY66108-11 to be used in batterypowered
applications over a wide spectrum of the battery
discharge curve.
