BROADCOM INTRODUCES FIFEM, THE WORLD’S FIRST WI-FI RF FEM WITH FILTER INTEGRATION OPTIMIZED FOR WI-FI 7 ACCESS POINTS

Broadcom Inc. announced the availability of its FBAR integrated front-end module (FiFEM™) devices for Wi-Fi access point (AP) applications, spanning Wi-Fi routers, residential gateways, and enterprise APs. The FiFEM devices incorporate best-in-class FBAR filter technology to provide superior 5 GHz and 6 GHz band coexistence and low in-band insertion loss while significantly reducing the bill of materials (BOM) at the RF front end. Additionally, the devices feature a state-of-the-art non-linear power amplifier (PA) design optimized for Broadcom’s Wi-Fi SoC Digital Predistortion (DPD) operation, enabling up to 40% reduction in RF front-end power.

The availability of the 6 GHz band for Wi-Fi has unlocked new opportunities for businesses and consumers across the globe through faster speed, lower latency, and higher capacity. To date, more than 60 countries have opened the 6 GHz band for Wi-Fi use providing the airspace for connected Wi-Fi 6E and Wi-Fi 7 devices to maximize their capabilities.

With the growing adoption of 6 GHz Wi-Fi in the market, the coexistence of 5-GHz and 6-GHz signals is a critical consideration for Wi-Fi 6E and Wi-Fi 7 AP designs. Further, the power dissipation in the 5 GHz and 6 GHz RF chains can be substantial, especially in a conventional tri-band 4x4 Wi-Fi AP system where RF power can reach 10 Watts per band. With RF filter integration and adaptive DPD, Broadcom’s FiFEM devices are highly optimized for Wi-Fi 7 AP systems delivering unprecedented size, performance, and efficiency.
