RF Power Amplifier Behavioral Modeling using MATLAB

Overview

In this webinar, you will learn how to model RF power amplifiers (PA) using measured data. We will excite a PA with a wideband 5G-like signal and capture the PA output signal. We will use MATLAB to create optimal behavioral models of the captured RF power amplifier data. We will compare different modeling techniques used to characterize the selected PA. Each of the modeling techniques will be verified and validated.

Highlights

Using PA measurements and model extraction techniques, we highlight:

• How you can use MATLAB on a NI PXI controller to collect PA data.
• Generation of test signals to drive a Power Amplifier connected to a NI PXIe-5841 VST.
• Use MATLAB to generate nonlinear PA models with and without memory
• Verify model performance by comparing simulated and measured outputs
