Qorvo has developed a new RF front-end module (FEM) for Wi-Fi 7 (802.11be) systems. The QPF4239 is a compact form factor along with integrated matching components, thereby minimizing the layout area in the application. It integrates a 2.4 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device. The performance of QPF4239 is focused on optimizing the PA for a 3.3 V supply voltage that conserves power consumption while maintaining the highest linear output power and leading-edge throughput.
This FEM’s integrated die level filtering for 2nd and 3rd harmonics as well as rejection in the 5 GHz band for DBDC operation are included to further enhance the signal quality. Additionally, a coupler with a broad range, constant slope voltage logarithmic power detector is provided for application feedback.
On the Tx chain, the QPF4239 delivers an output power of 19 dBm (802.11n) with a gain of 30 dB, while on the Rx chain, it provides a gain of 15.5 dB with a noise figure of 1.7 dB. It requires a DC supply of 3.3 V and consumes 14 mA (Rx) of current. This RoHS-compliant FEM is available in a laminate package that measures 3.0 x 3.0 mm and is ideal for access points, wireless routers, client equipment, customer premise equipment, and Internet of Things (IoT) applications.
The QPF4239 has a 5A991G export classification.
