SKYWORKS SE2431L-R

The SE2431L is a high-performance, fully integrated RF front-end module (FEM), suitable for Zigbee, Bluetooth Low Energy, and Bluetooth 1.0 applications. The SE2431L is designed for ease of use and maximum flexibility, with fully matched 50 Ω input and output, integrated inter-stage matching and harmonic filter, and digital controls that are compatible with 1.6 V to 3.6 V Complementary Metal Oxide Semiconductor (CMOS) levels. The RF blocks operate over a wide supply voltage range from 2.0 V to 3.6 V, which allows the SE2431L to be used in battery-powered applications over a wide spectrum of the battery discharge curve.
