Qorvo Inc of Greensboro, NC, USA (which provides core technologies and RF solutions for mobile, infrastructure and defense applications) says that its QPF4528 high-efficiency 5GHz front end module (FEM) is part of a new commercially available draft 802.11ax carrier gateway. The new gateway, which integrates Qualcomm Technologies Inc’s IPQ807x family of 802.11ax chipsets, provides up to four times higher wireless networking throughput and better performance in bandwidth-intensive applications than previously deployed carrier gateways.

As part of Qorvo’s 802.11ax portfolio of high-performance 2.4GHz and 5GHz FEMs, the QPF4528 transmits increased linear power without increasing power dissipation versus previous generations of FEMs. This reduces challenging thermal issues in the design of Wi-Fi equipment for multi-user multiple-input multiple-output (MU-MIMO) environments. The FEM’s power efficiency also enables applications that use Power over Ethernet (PoE), which is critical in regions of the world where output power is regulated.

“Our FEM powers Qualcomm Technologies’ IPQ8072 chipset solution for this milestone carrier gateway, delivering ever-increasing Wi-Fi throughput and expanded range,” says Cees Links, general manager of Qorvo’s Wireless Connectivity business unit, which develops wireless semiconductor system solutions for connected devices and Wi-Fi integrated front-end solutions, offering a range of RF chips and software for smart-home data communications and the Internet of Things (IoT). “Qorvo’s 802.11ax products are improving the experience of end users around the world, as more and more connected devices are used by everyone in the home,” he adds.

Market research firm IHS Markit estimates that global 802.11ax-enabled device shipments will reach nearly 200 million units by 2021.
