The Qorvo® QPF4578 is an integrated front end module (FEM) designed for Wi-Fi 802.11a/n/ac/ax systems. The compact form factor and integrated matching minimizes layout area in the application. Performance is focused on optimizing the PA for a 3.3 V supply voltage that conserves power consumption while maintaining the highest linear output power and leading edge throughput. The receive path is pinned out so external filtering can be added in the optimal position. Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included.
功率检测有两个选项，具有电压输出的直流功率检测器和具有来自定向耦合器的RF输出的RF功率检测器。QPF4578集成了5 GHz功率放大器（PA），单极两次投掷开关（SP2T）并绕过低噪声放大器（LNA）进入单个设备。
