K18D MATLAB Modeling Toolkit

Digital pre-distortion (DPD) is a common method to linearize the output signal of a power amplifier (PA), which is being operated in its non-linear operating range.

The R&S K18D application family offers a very easy-to-use method to pre-distort amplifiers without modelling the DUT.

However, many engineers in PA design request a simple and easy-to-use tool that delivers a DPD model applicable to any real-world signal.

This application note with the accompanying software tool allows engineers without in-depth knowledge of DPD or remote programming to generate a DPD model and verify it against the DUT, based on the results of the K18D application.
