2.4 GHz ZigBee®/Thread/Bluetooth® Smart Front-End Module

The SKY66112-11 is a high-performance, fully integrated RF front-end module (FEM) designed for ZigBee, Thread, and Bluetooth Smart applications.

The SKY66112-11 is designed for ease of use and maximum flexibility. The device provides an integrated inter-stage matching and harmonic filter, 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 1.8 V to 3.6 V that allows the SKY66112-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve.

Reference Designs

The SKY66112-11 FEM has been designed into reference designs with products from Dialog Semiconductor, Nordic Semiconductor, NXP, Texas Instruments and Silicon Labs. Combined with our partners’ platforms, the SKY66112-11 meets today’s demand for long-range, low-power and cost-effective solutions.
