QPF4211SR

QPF4211 2.4GHz Wi-Fi® 6 Front End Module

Qorvo QPF4211 2.4GHz Wi-Fi® 6 Front End Module (FEM) is designed for Wi-Fi 6 (802.11ax) systems. The QPF4211 integrates a 2.4GHz power amplifier (PA), regulator, single pole two throw switch (SP2T), bypassable low noise amplifier (LNA), and DC power detector into a single device. The small form factor and integrated matching of the QPF4211 minimize the layout area in the application. The 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. The receive path matches the optimal technologies to maximize Rx sensitivity through consistent noise figure performance over various conditions.
