Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QPF4291SR is an integrated dual front-end module (FEM) designed for Wi-Fi 6 (802 11ax) systems. The module allows two independent RF chains to operate through a single front-end module. The compact form factor and integrated matching capabilities minimise the layout area in the application and significantly reduce the number of external components. Performance focuses on optimising the multimode power amplifier for 3.85V supply voltages, resulting in the best throughput for user conditions.
