Product Overview

The Qorvo® QPF4209 is an integrated front end module (FEM)

designed for Wi-Fi 7 (802.11be) systems. The small form factor

and integrated matching minimizes layout area in the

application.

Performance is focused on optimizing the PA for a 5V supply

voltage that minimizes power consumption to allow for systems

that use digital pre-distortion to achieve the highest linear output

power and leading edge throughput for the RF chain.

A coupler with RF output is integrated for DPD feedback training.

For power control a broadrange, constant slope voltage

logarithmic power detector is provided for application feedback.

The QPF4209 integrates a 2.4 GHz power amplifier (PA), single

pole two throw switch (SP2T), coupler structure and bypassable

low noise amplifier (LNA) into a single device.
