2.4 GHz ZigBee®/Thread/Bluetooth® Front-End ModuleThe SKY66403-11 is a high-performance, fully integrated RF front-end module (FEM) designed for ZigBee, Thread, and Bluetooth (including Low Energy) applications.
The SKY66403-11 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 SKY66403-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve.
A functional block diagram is shown in Figure 1. The SKY66403-11 is provided in a small, 22-pin, 3.5 mm x 3.0 mm Multi-Chip Module (MCM) package.
The SKY66403-11 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 SKY66403-11 meets today’s demand for long-range, low-power and cost-effective solutions.
