The SKY66408-11 from Skyworks is a high-performance, fully integrated RF front-end module (FEM) designed for 2.4 GHz Zigbee, Thread, and Bluetooth (including Low Energy) applications. It is designed for ease of use and maximum flexibility. The module includes an integrated PA with an output power of up to +21 dBm, integrated LNA with a typical noise figure of 2.5 dB and an antenna diversity switch for all modes. It has integrated inter-stage matching, harmonic filtering, 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 module to be used in battery-powered applications over a wide spectrum of the battery discharge curve. It is available in a 24-pin multi-chip module (MCM) package that measures 3 x 3 mm and is suitable for use in appliances, smart thermostats, IoT devices, smart lighting, sensors, range extender and wireless audio.
