Qorvo QPF4216B Wi-Fi® Front End Module

Qorvo QPF4216B Wi-Fi® Front End Module is an integrated front-end module (FEM) designed for Wi-Fi 802.11ax systems. The compact form factor and integrated matching minimize the layout area in the application. Performance is focused on optimizing the power amplifier (PA) for a 5V supply voltage that conserves power consumption while maintaining the highest linear output power and leading-edge throughput. The receive path matches the optimal technologies to maximize Rx sensitivity through consistent noise figure performance 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 5GHz rejection for DBDC operation, is included. A key feature is the integration of a logarithmic power detector, which enables power control across the entire power spectrum for applications that use higher gain antennas or end users wanting to reduce device calibration time in production. The Qorvo QPF4216B integrates a 2.4GHz power amplifier (PA), regulator, single-pole two-throw switch (SP2T), and bypassable low noise amplifier (LNA) into a single device.
