QPF4211
Wi-Fi 6 Front End Module
®
Product Overview
The Qorvo® QPF4211 is an integrated medium power front end
module (FEM) designed for Wi-Fi 6 (802.11ax) systems. The
small form factor and integrated matching minimizes layout area
in the application.
Performance is focused on optimizing the PA for a 5V supply
voltage, while providing optional operation over a wide range,
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.
16 Pad 2.5 x 2.5 mm Laminate Package
