Qorvo launches first single FEM to support 5.1-7.1GHz bands
Qorvo Inc of Greensboro, NC, USA (which provides core technologies and RF solutions for mobile, infrastructure and defense applications) has introduced the first wideband Wi-Fi front-end module (FEM) covering the 5.1-7.1GHz bands for customer premises equipment (CPE). The new wideband QPF4730 can provide full-frequency support for both Wi-Fi 6 and Wi-Fi 6E enterprise solutions.
In previous generations of Wi-Fi routers, each radio is fixed to a specific frequency, due to the narrowband nature of available solutions. To enable broadband operation, manufacturers must currently place a 5GHz front-end module, a 6GHz front-end module and switch components. The QPF4730 flexibly delivers full high-band support while reducing the board space required in Wi-Fi 6E upgrades. This improves overall system performance, capacity and flexibility, says the firm.
“Qorvo’s newest FEM is optimized to operate over 5GHz, 6GHz or both, to maximize system capacity and throughput, which is not possible in existing CPE designs,” says Tony Testa, director of technical marketing. “Qorvo’s QPF4730 is the first in a family of new products that will address operational and architectural flexibility for Wi-Fi 6E channels and will include solutions for home gateways, routers and mesh systems.”
The QPF4730 enhances efficiency in Wi-Fi 6/Wi-Fi 6E architectures and is optimized for Power over Ethernet (PoE), improving Quality of Service (QoS), range and throughput. The solution maximizes user capacity and leverages the full available spectrum. It also enables manufacturers to design smaller form factors than current gateways to meet user expectations for more compact, sleek and efficient designs. With its expanded spectrum, Wi-Fi 6E provides higher throughput while servicing more client connections in home, campus and enterprise settings, say Qorvo.
