The QPF4617 from Qorvo is a 6 GHz Non-Linear, Integrated Front End Module (FEM) that is designed for Wi-Fi 6/6E applications. It consists of a 6-7 GHz power amplifier (PA), single pole two throw switch (SP2T), and bypassable low noise amplifier (LNA). This FEM has integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation. It also includes a coupler with RF output and a broadband logarithmic voltage detector application feedback. The module requires a DC supply of 5 V and consumes 225 mA of current in Tx mode and 29 mA of current in Rx mode. It is optimized to reduce power consumption while maintaining the highest linear output power and leading-edge throughput.
The QPF4617 provides a saturated output power of 32 dBm with a Tx gain of 31 dB and has an Rx noise figure of 1.9 dB. It is designed to operate in conjunction with DPD correction. This FEM is available in a surface-mount package that measures 5 x 3 mm and is ideal for use in access points, wireless routers, residential gateways, customer premise equipment, and IoT applications. The small form factor and integrated matching minimize the layout area in the application.
