QPF4219
Wi-Fi Front End Module
Product Overview
The Qorvo® QPF4219 is an integrated front end module (FEM)
designed for Wi-Fi 5 (802.11ac) 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.
Receive path matches the optimal technologies to maximize Rx
sensitivity through noise figure performance that is consistent
over a wider variety of conditions.
24 Pin 5x3 mm Laminate 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 5 GHz rejection for DBDC operation
are included.
