The Qorvo QPF7219 is an integrated front end module (iFEM) designed for Wi-Fi 6 (802.11ax) systems which marries the advantages of active components with BAW filter technology. The compact form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. Performance is focused on optimizing the PA for a 5 V supply voltage that conserves power consumption while maintaining the highest linear output power and leading edge throughput across all Wi-Fi channels 1 through 11 without need to reduce transmit power to meet the FCC regulatory limits. Receive path matches the optimal technologies to maximize Rx sensitivity through noise figure performance that is consistent over a wider variety of conditions.
The receive path is pinned out so external filtering can be added in the optimal position. Integrated die level filtering for 2nd and 3rd harmonics as well as 5 GHz rejection for DBDC operation are included.
The QPF7219 integrates a 2.4 GHz power amplifier (PA) with power detector, FCC bandedge BAW filter, regulator, transmit-receive switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
