QPF7219 Wi-Fi® Integrated Front End Module Qorvo QPF7219 Wi-Fi® Integrated Front End Module (iFEM) is designed for Wi-Fi 6 (802.11ax) systems which combine the advantages of active components with BAW filter technology. This iFEM optimises the power amplifier (PA) for a 5V supply voltage to conserve power while maintaining the highest linear output power. The QPF7219 iFEM also achieves leading throughput across all Wi-Fi channels 1 to 11 without the need to reduce transmit power to meet the FCC regulatory limits. This iFEM offers integrated die-level filtering for 2nd and 3rd harmonics as well as 5GHz rejection for DBDC operation.
