QPF4578
Wi-Fi Front End Module
Product Overview
The Qorvo® QPF4578 is an integrated front end module (FEM)
designed for Wi-Fi 802.11a/n/ac/ax systems. The compact form
factor and integrated matching minimizes layout area in the
application.
Performance is focused on optimizing the PA for a 3.3V supply
voltage that conserves power consumption while maintaining
the highest linear output power and leading edge throughput.
24 Pin 5x3 mm QFN Package
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 2.4 GHz rejection for DBDC operation
are included.
Key Features
• 5150ꢀ–ꢀ5925ꢀMHz

There are two options for power detect, a DC power detector
which has voltage output and an RF power detector with an RF
output from a directional coupler.
The QPF4578 integrates a 5 GHz power amplifier (PA), single
pole two throw switch (SP2T) and bypassable low noise
amplifier (LNA) into a single device
