QPF4588ASR

RF Front End (LNA + PA) Overview

The Qorvo QPF4588ASR is an integrated front-end module (FEM) designed for Wi-Fi 6 (802.11ax) systems operating in the 5.15 GHz to 5.895 GHz range. It integrates a power amplifier, low-noise amplifier, switch, and coupler within a compact 24-QFN package measuring 5x3 mm. The device is optimized for +5 V operation, delivering up to +26 dBm output power with compliant spectral masks. Key electrical parameters include 33 dB transmit gain, 2 dB noise figure, and 16 dB receive gain.
