QPF4239 Front End Module by Qorvo
The QPF4239 from Qorvo is a Wi-Fi 7 (802.11be) Front-End Module (FEM) that operates from 2412 to 2484 MHz. It consists of a 2.4 GHz power amplifier (PA), single pole two throw switch (SP2T), and by-passable low noise amplifier (LNA). This FEM also has an RF output coupler and a broad-range, constant slope voltage logarithmic power detector for application feedback.
In the Tx path, it delivers an output power of 19 dBm with a gain of 30 dB while on the Rx side, it provides a gain of 15.5 dB and has a noise figure of 1.7 dB. The FEM 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 3.3 V and consumes less than 185 mA of current. It is available in a 16-Pad laminate package that measures 3.0 x 3.0 mm. This FEM is ideal for access points, wireless routers, IoT, customer premise equipment, and set-top box applications.
