QM42500 Wi-Fi® 7 Front End Module

The Qorvo QM42500 is an integrated mobile Wi-Fi FEM designed for Wi-Fi 7 (802.11be) systems. The small form factor and integrated matching minimize the layout area in the application.

Performance is focused on optimizing the PA for a broad range of supply voltage (3.0 V < V_CC < 5.0 V). The multiple Wi-Fi and BT TX modes enable optimization of output power, linearity, and power dissipation, conserving power consumption while maintaining the highest linear output power and leading edge throughput. The receive path matches the optimal technologies to maximize Rx sensitivity through consistent noise figure performance over a wider variety of conditions.

Integrated die level filtering for 2nd and 3rd harmonics as well as 5 GHz rejection for DBDC operation are included. An integrated power coupler enables close loop power control and DPD optimization.

The QM42500 integrates a multi-TX state 2.4 GHz Wi-Fi power amplifier (PA) that is also used for HP BT, single pole four throw switch (SP4T) ANT switch, bypassable low noise amplifier (LNA) with multiple RX states, and power coupler into a single device.
