Abstract

Using a nonlinear black-box model based on the Volterra theory it is possible to describe the nonlinear behaviour of a high frequency amplifier. Acquiring only a strongly reduced set of measurements it is easy to predict the load impedance curves anywhere on a Smith Chart. The classic load-pull approach involves the acquisition of a large amount of data and still lacks a description of the nonlinear behaviour of the amplifier in deviating situations
