DATA SHEET RFX2411N: 2.4 GHz Transmit / Receive Booster with Diversity Switch for IoT / BLE / Zigbee Applications Extended range devices Zigbee, ANT+, Thread, Bluetooth, BLE, RF4CE Smart energy / metering / lighting / remote control Home and industrial automation Custom 2.4 GHz radio systems Mobile and battery systems Features Single-chip, single-die CMOS IC Transmit/receive switch circuitry Antenna diversity switch circuitry Figure 1. RFX2411N Block Diagram TX power amplifier or bypass RX low-noise amplifier or bypass Description Linearity in compliance with standards for OQPSK, DQPSK, The RFX2411N is a fully integrated, single-chip, single-die and 8DPSK modulations RFeIC (RF front-end integrated circuit) that incorporates all the Integrated power detector for transmit power monitor and RF functionality needed for wireless Zigbee / smart energy control applications. The RFX2411N architecture integrates TX / RX and diversity switching circuitry with PA, LNA, and the associated CMOS control logic matching networks with harmonic reduction in a CMOS ESD protection circuitry on all pins single-chip device. The device also includes a bypass mode to RF ports do not carry DC voltage provide maximum flexibility for system implementations. Internal RF decoupling on VDD bias pins The RFX2411N is designed for the 2.4 GHz ISM band and Very low DC power consumption supports Bluetooth / BT EDR / BLE, 802.15.4, Zigbee, ANT, and Thread. The RFX2411N is the perfect solution for applications Operation up to 125 C ambient temperature requiring extended range and bandwidth, such as home and Full on-chip matching and decoupling circuitry industrial automation, smart energy/smart metering, and Minimal external components required RF4CE. RFX2411N interfaces seamlessly with low-voltage CMOS control logic, requires minimal external components, and 50 input/output matching provides an integrated PA power detector circuit. The superior Market-proven CMOS technology performance, high sensitivity, high efficiency, low noise, small Small QFN (20-lead,3.0 x 3.0 x 0.55 mm) package with form factor, low power consumption and low cost make the exposed ground pad RFX2411N an ideal and application-friendly solution.
