The Skyworks RFX2401C data sheet provides specifications, pinout, electrical ratings and application guidelines for the 2.4 GHz ZigBee/ISM front‑end module.
The RFX2401C is a fully integrated 2.4 GHz ZigBee/ISM front‑end module that combines a PA, LNA, transmit/receive switch and matching network in a 16‑pin QFN package. It is intended for extended‑range ZigBee devices, smart‑power, wireless audio, home and industrial automation, and custom 2.4 GHz radio systems.
Key electrical specifications include a saturated output power of +22 dBm, small‑signal gain up to 26.5 dB, and a low noise figure of 2.5 dB. The device operates from a 2.0 V to 3.6 V supply, draws 17 mA in TX quiescent mode, and is packaged in a 3 mm × 3 mm × 0.55 mm QFN with an exposed ground pad for efficient heat dissipation.
