Original 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.
