The QPF4750 from Qorvo is a Wi-Fi 6E (802.11ax) Front-End Module (FEM) that operates from 5 to 7 GHz. It integrates a power amplifier (PA), a single pole two-throw (SP2T) switch, and a bypassable low noise amplifier (LNA) into a single device. This FEM implements very wideband amplifier technology to create an easier to use and extremely compact solution for Wi-Fi applications that operate on any channel within U-NII1-8’s 2 GHz of bandwidth.
On the Tx side, it delivers an output power of 20 dBm with a gain of 32 dB while on the Rx side, it provides a gain of 14 dB and has a noise figure of 2 dB. The receive path of this module matches the optimal technologies to maximize receive sensitivity through noise figure performance that is consistent over a wide variety of conditions. It has integrated die-level filtering for second and third harmonics as well as 2.4 GHz rejection for DBDC operation. This module requires a DC supply of 5 V and consumes 25 mA (Rx) of current. It is available in a laminate package that measures 3.0 x 3.0 mm. The Front-end module is ideal for access points, wireless routers, IoT, customer premise equipments, and set-top box applications.
