QPF4219 Integrated Front-End Modules

Qorvo QPF4219 Integrated Front-End Modules (FEM) are designed for use in Wi-Fi® 5 (802.11ac) systems. QPF4219 modules integrate 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. Applications include wireless routers, residential gateways, customer-premise equipment, and the Internet of Things (IoT). Qorvo QPF4219 Integrated FEMs' compact form factor and integrated matching minimize the layout area in the application. The devices optimize the PA with a 5V supply voltage that conserves power consumption while maintaining the highest linear output power. QPF4219 receive paths to match the optimal technologies to maximize Rx (receive) sensitivity through noise figure performance.
