Qorvo 5 GHz Wi-Fi 6 U-NII2c-3 bandBoost Integrated Front End Module QPF7552

The Qorvo® QPF7552 is an integrated high power front end module (iFEM) designed for Wi-Fi 6 (802.11ax) systems. This iFEM integrates bandBoost technology to create an easier to use and extremely compact solution for Wi-Fi tri-band applications where operating in two radios simultaneously within the 5GHz frequency band is needed. The small form factor and integrated matching minimizes layout area in the application. Performance is focused on optimizing the PA for a 5V supply voltage, while providing optional operation over a wide range, that conserves power consumption while maintaining the highest linear output power and leading edge throughput. Qorvo bandBoost technology is integrated to allow operation in UNII2c3 while reducing out of band power in UNII1-2a to a level that is appropriate for use on the same board. Receive path matches the optimal technologies to maximize Rx sensitivity through noise figure performance that is consistent over a wider variety of conditions. Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included. For application feedback, a DC power detector is integrated in the package providing a proportional voltage for a given output power from the transmit path. The QPF7552 integrates a 5 GHz power amplifier (PA), UNII2c3 bandBoost BAW filter, single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
