Qorvo has launched an integrated front-end module (iFEM) that provides reliable, whole-home coverage when designed into Wi-Fi 6 (802.11ax) systems. The iFEM combines Qorvo's advanced BAW filter technology with its unique edgeBoost – or flat power – capability, nearly doubling Wi-Fi range and tripling capacity to handle more devices.
The Wi-Fi Alliance forecasts as many as 50 billion connected wireless devices around the world by 2022. The new Qorvo QPF7219 opens up the full 2,4 GHz Wi-Fi bandwidth, making it all usable throughout the smart home and delivering extended FCC-compliant range.
The QPF7219 integrates a 2,4 GHz power amplifier (PA) with power detector, FCC edgeBoost BAW filter, regulator, transmit-receive switch and bypassable low-noise amplifier into a single device. This removes 20 surface mount components based on a 4x4 configuration, reducing printed circuit board area by 40% compared to standalone solutions.
The PA's performance, optimised for a 5 V supply voltage, conserves power while maintaining high linear output power and throughput across all Wi-Fi channels 1 through 11. This eliminates the need to reduce transmit power (flat power) to meet FCC regulatory limits. It makes range, capacity and coexistence improvements across all available channels, significantly increasing quality of service.
Qorvo edgeBoost provides flat-power capability that maximises capacity and range by boosting output power at channels close to the band edge.
