The Qorvo® QPF4557 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. This is done across a wide bandwidth enabling operation in all channels from UNII1-3 (5.125 to 5.925 GHz).
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 QPF4557 integrates a 5 GHz power amplifier (PA), single pole two throw switch (SP2T), coupler structure and bypassable low noise amplifier (LNA) into a single device.
