The Qorvo® QPF4506 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 5 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 has integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included.

For power accuracy feedback a integration of a DC power detector with logarithmic feedback across power which enables power control to lower powers and enables the possibility to calibrate against a constant slope for applications which use higher gain antennas or end users wanting to reduce device calibration time in production.

The QPF4506 integrates a 5 GHz power amplifier (PA), regulator, single-pole two throw switch (SP2T), and a bypassable low noise amplifier (LNA).
