Product Overview
The Qorvo® QPF4551 is an integrated front end module (FEM)
designed for Wi-Fi 6 (802.11ax) systems. The compact form
factor and integrated matching minimizes 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.
16 Pad 2.5 x 2.5 mm Laminate Package
Key Features
Integrated die level filtering for 2nd and 3rd harmonics as well
as 2.4 GHz rejection for DBDC operation are included.
