The QPF4528 front end module (FEM) from Qorvo is now in stock at Mouser Electronics. Designed for Internet of Things (IoT) systems based on Wi-Fi 6, the 5 GHz FEM offers a compact form factor and integrated matching to minimise layout area in applications such as wireless routers, set top boxes, and access points.

The FEM integrates a 5GHz power amplifier (PA), regulator, single-pole double-throw (SPDT) switch, low noise amplifier (LNA) with bypass mode, RF coupler, and voltage power detector into a single device.

It boosts linear power transmission without increasing power dissipation, enabling higher-performance Wi-Fi 6 (802.11ax) enterprise access points in smaller form factor designs.

The module allows up to 8×8 multiple-input multiple-output (MU-MIMO) in both conventional and Power over Ethernet (PoE) systems, offering fewer access points, enhanced capacity and efficiency, improved speed, and reduced operating costs across enterprise systems.

It is also optimised to solve thermal challenges in Wi-Fi equipment designed for MU-MIMO environments.
