WiFi7 FEM Qorvo QPF4239

The Qorvo QPF4239 is an integrated front end module (FEM) designed for Wi-Fi 7 (802.11be) systems. The compact form factor and integrated matching minimises layout area in the application.

Performance is focused on optimising the PA for a 3.3V 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 5 GHz rejection for DBDC operation are included. A coupler with RF output as well as a broad range, constant slope voltage logarithmic power detector is provided for application feedback.

The QPF4239 integrates a 2.4 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
