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.
