Qorvo QPF4519 Wi-Fi® Front End Module

Qorvo QPF4519 Wi-Fi® Front End Module is housed in a compact form factor and designed for Wi-Fi 802.11a/n/ac systems. The QPF4519 features integrated matching that minimizes the 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. 

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 and 2.4GHz rejection for DBDC operation are included. The QPF4519 integrates a 5GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
