QPF4230 Wi-Fi® Front End Module (FEM) Qorvo QPF4230 Wi-Fi® Front End Module (FEM) is designed for Wi-Fi 6 (802.11ax) systems. This module integrates a 2.4GHz power amplifier (PA), regulator, single-pole three-throw (SP3T) switch, low-noise amplifier (LNA), and coupler into a single device. The performance is focused on optimizing the PA for 3.3V supply voltage to conserve power consumption while maintaining the highest linear output power and leading-edge throughput. The compact form factor of the QPF4230 FEM and its integrated matching minimizes layout area in the application. The QPF4230 RF FEM is ideally used in wireless routers, access points, client equipment, customer premise equipment, and Internet of Things (IoT).
