            QPF4559 5 GHz Wi-Fi® 7 High-Power Front End Module
                    The Qorvo QPF4559 module integrates a 5 GHz power amplifier, single pole two throw switch (SP2T), and a bypassable low noise amplifier (LNA) into a single device
    

The Qorvo QPF4559 integrated front-end module (FEM) is designed for Wi-Fi 7 (802.11be) 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 5 V supply voltage that conserves power consumption while maintaining the highest linear output power and leading edge throughput. This is done across a wide bandwidth, enabling operation in all channels from UNII1-4 (5.1 GHz to 5.9 GHz). Integrated die level filtering for 2^nd and 3^rd harmonics and 2.4 GHz rejection for DBDC operation are included. A coupler with RF output and a broad range, constant slope voltage logarithmic power detector is provided for application feedback.

The Qorvo QPF4559 integrates a 5 GHz PA, SP2T switch, and bypassable LNA into a single device.
