QM42655SR

RF Front End (LNA + PA) Overview

The Qorvo QM42655SR is an integrated mobile Wi-Fi front-end module (FEM) tailored for Wi-Fi 7 (802.11be) applications, specifically operating in the 2.4 GHz band. It features a compact footprint with built-in matching components to reduce layout area. The module delivers optimal performance across a wide input voltage range of 3.0 V to 5.0 V. Key electrical parameters include P_OUT = +16.5 dBm at MCS13 HE40 with -47 dB dynamic EVM, and P_OUT = +20.0 dBm at MCS7 HT40 with -39 dB dynamic EVM. It offers 32 dB Tx gain, a 1.7 dB noise figure, and Rx gains of 17 dB (high gain) or 15 dB (low current).
