5 GHz Medium Power Wi-Fi 6 FEM

Wi-Fi 6 Front End Module: QPF4550

April 22, 2021

RFMW announced design and sales support for a Wi-Fi 6  (802.11ax) front end module (FEM). The Qorvo QPF4550 offers a compact form factor with integrated matching, minimizing wireless access point layout area. Performance is focused on optimizing the power amplifier (PA) for a 5 V supply voltage that conserves power consumption while maintaining the highest linear output power and leading edge throughput with Pout = +24.5 dBm MCS0 HT20 spectral mask compliance. Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included. The QPF4550 integrates a 5 GHz PA, single pole two throw switch and bypassable low noise amplifier into a single device.
