Wi-Fi Front End Module
Product Overview
The Qorvo® RFFM8228P is an integrated front end module
(FEM) designed for Wi-Fi 802.11a/n/ac systems. The compact
form factor and integrated matching minimizes layout area in
the application.
Performance is focused on a balance of efficiency versus
linear power that increases the range and throughput of
connections. Control ines are reduced to a two pin scheme.
16 Pin 2.3x2.3 mm QFN Package
Key Features
Integrated die level filtering for 2nd and 3rd harmonics are
included.
The RFFM8228P integrates a 2.4 GHz power amplifier (PA),
single pole three throw switch (SP3T) and low noise amplifier
(LNA) into a single device.
