High Power Front End Module: QPF4658
The Qorvo QPF4658 is an integrated front end module (FEM) designed for Wi-Fi 6 & 6E (802.11ax) systems. The small 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. This is done across a wide bandwidth enabling operation in all channels from UNII5-8 (5.9 to 7.1 GHz). Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included. A coupler with RF output as well as a broadband logarithmic voltage detector is provided for application feedback.
The QPF4658 integrates a 6 - 7 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
