QPF4219
Wi-Fi Front End Module
Product Overview
The Qorvo® QPF4219 is an integrated front end module (FEM)
designed for Wi-Fi 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
Key Features
2400-2500ꢀMHz
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.
