2.4 GHz Front-End Module for Bluetooth® Low Energy/802.15.4/Thread/Zigbee®

The SKY66114-11 is a high-performance, fully integrated RF front-end module (FEM) designed for Bluetooth Low Energy, 802.15.4, Thread and ZigBee applications.

The SKY66114-11 is designed for ease of use and maximum flexibility. The device integrates a high-efficiency saturated PA, high-gain LNA, T/R and bypass switches, and digital controls compatible with 1.6 V to 3.6 V CMOS levels.

The RF blocks operate over a wide supply voltage range from 1.2 V to 3.6 V that allows the SKY66114-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve.

The SKY66114-11 is provided in a small, 16-pin, 2.4 × 2.4 mm Multi-Chip Module (MCM) package.

Evaluation Board
Evaluation Board SKY66114-11EK1 is available.
