QPF4750

The Qorvo® QPF4750 is an extreme wideband medium power front end module (FEM) designed for Wi-Fi 6E (802.11ax) systems. This FEM implements extreme wideband amplfier technology to create an easier to use and extremely compact solution for Wi-Fi applications where operating on any channel within U-NII1-8’s 2GHz of bandwidth is deisred. The small form factor and integrated matching minimizes layout area in the application.

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. 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 QPF4750 integrates a 5 - 7 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
