Abstract: Signal predistortion occurs in modern communication systems and in other systems requiring linear signal amplification. The objective is to learn about signal predistortion, the QORVO 1800 MHz FDD radio front-end and to implement the front-end control using RFSoC and Matlab computer program. I focus on controlling individual attenuators and amplifiers on the QORVO front-end with a program written in C. Using a single board computer Raspberry Pi 4B running Linux. Furthermore, the work involves the application of a SCPI server that operates based on TCP packets. As part of the introduction to the front-end, the power characteristic of the power amplifier is measured.
