The RFX2411 is a fully integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates all the RF functionality needed for wireless ZigBee / smart energy applications. The RFX2411 architecture integrates the PA, LNA, Transmit and Receive switching circuitry, the associated matching network, a harmonic filter and a diversity switch all in a CMOS single-chip device. It also includes a bypass mode to provide maximal level of flexibility for system implementations.

This RFeIC is designed for use in 2.4GHz ISM band and supports the 802.15.4 and ZigBee standard. Typical high power applications include home and industrial automation, smart power, and RF4CE among others. Combining superior performance, high sensitivity and efficiency, low noise, small form factor, and low cost, RFX2411 is the perfect solution for applications requiring extended range and bandwidth. RFX2411 has simple and low-voltage CMOS control logic, and requires minimal external components for system implementation. The PA power detect circuit is also integrated.
