The Qorvo® QPF4607 is an integrated front end module (FEM) designed for Wi-Fi 7 (802.11be) systems. The compact 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. This is done across a wide bandwidth enabling operation in all channels from UNII5-8 (5.945 to 7.125 GHz)
A coupler with RF output is integrated for DPD feedback training. Options for alternate routing of the feedback are included with low loss. For power control a broadrange, constant slope voltage logarithmic power detector is provided for application feedback. The module includes a state to turn the FEM on and off, which could reduce bill of material or give an option to reduce current draw.
The QPF4607 integrates a 6 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable multi-mode low noise amplifier (LNA) into a single device.
