    • 65 dB 2.4 GHz Rejection on Rx Path
    • Integrated DC Power Detector

    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 UNII1- 2a while reducing out of band power in UNII2c-3 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 QPF7551 integrates a 5 GHz power amplifier (PA), UNII1- 2a bandBoost BAW filter, single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
