Qorvo QPF4516B Wi-Fi® Front End Module
Qorvo QPF4516B Wi-Fi® Front End Module is an integrated front-end module (FEM) designed for Wi-Fi 6 802.11ax 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 and 2.4GHz rejection for DBDC operation are 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 QPF4516B integrates a 5GHz PA, regulator, single-pole two-throw switch (SP2T), and bypassable low-noise amplifier (LNA) into a single device.
The Qorvo QPF4516B Wi-Fi Front End Module is lead-free, halogen-free, and RoHS compliant in a 5.0mm x 3.0mm laminate package.
