QPF4530 5GHz Wi-Fi® Front End Module Qorvo QPF4530 5GHz Wi-Fi® Front End Module is a highly integrated device designed for Wi-Fi 6 (IEEE 802.11ax) applications. The QPF4530 Front End Module (FEM) combines a 5GHz power amplifier (PA), regulator, single-pole two-throw switch (SP2T), and a bypassable low noise amplifier (LNA) into a single device. The QPF4530 features a compact form factor and integrated matching, minimizing layout area in the application.
