Qorvo QPF4800 Wi-Fi 6 front-end module

Qorvo’s QPF4800 Wi-Fi 6 front-end module (FEM) is designed for Wi-Fi 6 (802.11ax) applications, combining the high performance levels required to transfer HD and 4K video with the efficiency necessary for Internet of Things (IoT) applications. The highly integrated FEM is suitable for a range of Wi-Fi 6 applications, including wireless routers, customer premises equipment, access points, set-top boxes and residential gateways.

The dual-band FEM features 2.4 and 5 GHz power amplifiers; two single-pole, double-throw (SPDT) switches; a regulator; a diplexer; and a low-noise amplifier with bypass. It is designed to support increased users per access point, increased per-user traffic demand, higher-density deployments, increased cellular offloading, and additional power and performance in Wi-Fi 6 applications.

The high-performance FEM provides a transmit gain of over 29 dB and a receive gain of 14 dB, with a 2.6 dB noise figure when operating over a 5 V supply. Additionally, it provides the required density, capacity and thermal performance for 4x4 MIMO operation.
