BAW filter powered range-enhancing Wi-Fi FEM for smart home and IoT

Date: 22/09/2022
The new Wi-Fi front-end module from Qorvo solves some of the typical Wi-Fi routers problems inside a home such as range, capacity and power efficiency. This is possible due to Qorvo's own edgeBoost bulk acoustic wave filtering technology. Qorvo says its unique flat power capability maximises capacity and range by maximising output power at channels close to the band edge.

QPF7250 packs 2.4 GHz power amplifier with DC and RF power detectors, an FCC edgeBoost BAW filter, a transmit or receive select switch and a bypassable low noise amplifier (LNA) into a single module.

Qorvo claims its compact QPF7250 iFEM extends range by 30% compared to other devices in the market supporting Wi-Fi 6 (802.11ax) and eventually Wi-Fi 7 systems without compromising on the quality of service.

The QPF7250 iFEM enables use of more access points for Wi-Fi dependent smart homes and the Internet of Things (IoT).

Qorvo is also optimised the power amplifier of this module to consume 0.35 Watt lower power over predecessors.

Tony Testa, Qorvo director of Wireless Connectivity Product Marketing, said, "Qorvo's newest Ifem provides superior power efficiency up to 1.4 Watt savings in a 4-stream router better than any other integrated FEM. The very compact QPF7250 makes possible smaller, less intrusive access points and wireless routers. This device is the latest in a growing Qorvo family of highly integrated products that will address operational and architectural flexibility for Wi-Fi 6 and 7 systems, and includes solutions for home gateways, routers and enterprise deployments."

QPF7250 Ifem consumes 15% less power while delivering 10% range enhancement through higher regulatory-compliant power and leading throughput across Wi-Fi channels 1 through 11.

Qorvo says its iFEMs offers cost and time advantages such as lesser time to market, assured RF tested performance, less number of components to save BOM cost.

QPF7250 is sampling now with production volumes available from Qorvo and authorized distributors.
