    The Qorvo QPF4538 is an integrated front end module (FEM) designed for Wi-Fi 802.11a/n/ac systems. The compact form factor and integrated matching minimizes layout area in the application.

    Performance is focused on optimizing the PA for PoE applications by centering on 0.5W 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 QPF4538 integrates a 5 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
