860 to 930 MHz RF Front-End Module

The SKY66422-11 is a high-performance, highly integrated RF front-end module designed for high-power Industrial, Scientific, Medical (ISM) band applications operating in the 860 to 930 MHz frequency range.

The SKY66422-11 is designed for ease of use and maximum flexibility with fully matched 50 Ω TX and RX inputs, and digital controls compatible with 1.6 to 3.6 V CMOS levels.

The RF blocks operate over a wide supply voltage range from 2.5 to 3.6 V allowing the SKY66422-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve. The SKY66422-11 is packaged in a 16-pin, 3.0 x 3.0 x 0.75 mm Multi-Chip Module (MCM) package.
