    The Qorvo QPF4219 is an integrated front end module (FEM) designed for Wi-Fi 802.11ac systems. The compact form factor and integrated matching minimizes layout area in the application.

    Performance is focused on optimizing the PA for a 5V 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 is pinned out so external filtering can be added in the optimal position.  Integrated die level filtering for 2nd and 3rd harmonics as well as 5 GHz rejection for DBDC operation are included.

    The QPF4219 integrates a 2.4 GHz power amplifier (PA), regulator, single pole two throw switch (SP2T), bypassable low noise amplifier (LNA) and DC power detector into a single device.
