2.4 GHz TX / RX Booster With Diversity Switch for IoT / BLE / ZigBee

The RFX2411N 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 RFX2411N architecture integrates a TX/RX and diversity switching circuitry with PA, LNA, and the associated matching networks with harmonic reduction all in a CMOS single-chip device. It also includes a bypass mode to provide maximal level of flexibility for system implementations.

RFX2411N is designed for the 2.4GHz ISM band and supports standards like Bluetooth/BT EDR/ BLE, 802.15.4, ZigBee, ANT and Thread. RFX2411N is the perfect solution for applications requiring extended range and bandwidth. Typical high power applications include home and industrial automation, smart energy / smart metering, and RF4CE among others. RFX2411N interfaces seamless with low-voltage CMOS control logic, requires minimal external components, and provides even an integrated PA power detector circuit. Combining superior performance, high sensitivity, high efficiency, low noise, small form factor, low power consumption and low cost, RFX2411N provides an ideal and application-friendly solution.
