Linearization Of RF Amplifiers

This white paper is based on collaborative work between MathWorks® and Rohde & Schwarz. The focus is on linearization of a non-linear device, in our case the RF power amplifier. It is shown how simulation and the integrated functions of the Rohde & Schwarz instruments R&S®SMW200A and R&S®FSW work hand-in-hand with the simulation capabilities from MathWorks in MATLAB / Simulink. The goal is to provide a toolset to enable proper modeling and linearization approaches to optimize and verify the behavior of the power amplifier when used with complex wideband signals as used in 5G NR or latest satellite links.
