    The Qorvo QPF8248 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 a balance of efficiency versus linear power that increases the range and throughput of connections.   Control lines are reduced to a two pin scheme.

    Integrated die level filtering for 2nd and 3rd harmonics as well as 5GHz rejection for DBDC operation are included.

    The QPF8248 integrates a 2.4 GHz power amplifier (PA), single pole three throw switch (SP3T) and low noise amplifier (LNA)  into a single device.
