Overview
The RFX2401C from Skyworks Solutions Inc. is a fully integrated, single-chip, single-die RF Front-end Integrated Circuit (RFeIC) designed to operate in the 2.4 GHz ISM band. This CMOS device incorporates all the necessary RF functionality for IEEE 802.15.4/ZigBee, wireless sensor networks, and other wireless systems. It combines a power amplifier (PA), low noise amplifier (LNA), transmit and receive switching circuitry, associated matching network, and harmonic filter into a single, compact package. The RFX2401C is ideal for applications requiring extended range and bandwidth, such as home and industrial automation, smart power, and RF4CE, due to its superior performance, high sensitivity, efficiency, low noise, and small form factor.
