902 to 931 MHz High-Power RF Front-End Module

The SKY66105-11 is a high performance, highly integrated RF Front-End Module (FEM) designed for high power Industrial, Scientific, and Medical (ISM) applications operating in the 902 MHz to 931 MHz frequency band.

The SKY66105-11 is designed for ease of use and maximum flexibility, with fully matched 50 Ω inputs and outputs, and digital controls compatible with 1.8 V to 3.6 V CMOS levels.

The RF blocks operate over a wide supply voltage range from 2.0 V to 4.8 V, which allows the SKY66105-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve.

The SKY66105-11 is packaged in a 12-pin, 8 x 6 mm Multi-Chip Module (MCM) with exposed ground paddle and surrounding shielding.
