Broadcom has launched Film Bulk Acoustic Resonator (FBAR) integrated front-end module (FiFEM) devices for Wi-Fi access points, which the company claims ensures coexistence in the 5 GHz and 6 GHz bands while minimizing in-band insertion loss. Additionally, they significantly reduce the bill of materials (BOM) at the RF front end. The devices feature a non-linear power amplifier (PA) design, specially optimized for Broadcom’s Wi-Fi System on a Chip (SoC) Digital Predistortion (DPD) operation. This optimization allows an impressive up to 40% reduction in RF front-end power consumption. These devices are designed for Wi-Fi routers, residential gateways, and enterprise Access Points (APs). The introduction of the 6 GHz band for Wi-Fi has opened up new possibilities for businesses and consumers worldwide, offering faster speed, lower latency, and higher capacity.

 It is the First non-linear FEM qualified for WiFAM Gen2. The FiFEM devices are designed to meet Wi-Fi 7 AP system specifications and are available in four different products, each housed in a conventional Front-End Module (FEM) package. These devices are ready to optimize Wi-Fi access points, providing exceptional performance and power efficiency with the company’s SoC reference designs.

Some of the key features of the devices include:

  • High Power Pout +25dBm, MCS0 20MHz
  • High Power Pout +23dBm, MCS0 20MHz
  • Broadcom WiFAM Gen-2 Certified (Wireless FEM Active Management)
  • Compatible with Dynamic Bias Handling Technology
  • 24 pins surface mounting package
  • Integrated Detector
  • Small Size (3.0×5.0mm)
  • Package Height 0.8mm
  • WCC Reference Design
  • Internal 50 Ω matching networks for both RF input and output
  • Green – Lead-free and RoHS compliant

“Broadcom has shipped billions of highly integrated RFFE modules to the cellular market. Our Wi-Fi 7 FiFEM devices leverage this deep integration expertise via our FBAR and high-efficiency PA technology,” said Youngwoo Kwon, senior vice president and general manager of the Wireless Semiconductor Division at Broadcom. “We’re excited to contribute to the widespread deployment of Wi-Fi 7 systems with our industry-leading performance, low power, high-efficiency 5-GHz and 6-GHz FiFEM devices.”
