Qorvo’s QPF7219 integrated front end module (iFEM) is now being shipped by distributor Mouser Electronics.

Providing reliable, whole-home coverage when designed into Wi-Fi 6 (802.11ax) systems, the QPF7219 iFEM combines Qorvo's advanced bulk acoustic wave (BAW) filter technology with its unique edgeBoost capability to almost double Wi-Fi range and triple capacity to handle more devices.

The Qorvo QPF7219 Wi-Fi 6 iFEM integrates a 2.4GHz power amplifier (PA) optimised for a 5V supply voltage, which saves power while maintaining high linear output power.

The BAW filter's edgeBoost capability maximises output power at channels close to the band edge, achieve excellent throughput across all Wi-Fi channels 1-11 without needing to reduce transmit power to meet FCC regulatory limits.

The module also includes a bypassable low noise amplifier, regulator, and transmit-receive switch.

The device offers 5GHz rejection for dual-band dual-concurrent (DBDC) operation, as well as integrated die-level filtering for second and third harmonics.

The QPF7219 iFEM is ideal for a range of connectivity solutions, including wireless routers, access points, residential gateways, Wi-Fi customer premises equipment, and Internet of Things (IoT) applications.

For development, Mouser also stocks the QPF7219EVB-01 evaluation board.
