Qorvo 5 GHz Wi-Fi Front End Module QPF4530

The Qorvo® QPF4530 is an integrated front end module (FEM) designed for Wi-Fi 802.11ax 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. Receive path matches the optimal technologies to maximize Rx sensitivity through noise figure performance that is consistent over a wider variety of conditions. 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. A DC power detector which has voltage output provides feedback for close loop applications. The QPF4530 integrates a 5 GHz power amplifier (PA), regulator, single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
