WiFi 6 FEM incorporates Power Detector

RFMW announces design and sales support for a Wi-Fi 6 (802.11ax) front end module (FEM). The Qorvo QPF4551 offers a compact form factor with integrated matching, minimizing wireless access point layout area. Performance is focused on optimizing the PA for a 5 V supply voltage that conserves power consumption while maintaining the highest linear output power and leading edge throughput. Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included. The QPF4551 integrates a 5 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
