Abstract :
In this paper we show how a thin-plate spline approximation can be used to generate a model of the measured response surface of a load-pull measurement over a much-reduced number of impedance points with no significant loss of accuracy. Further, interpolation between these model surfaces is possible, generating accurate drive-up characteristics. This has enabled accurate load-pull characterizations to be made in a fraction of the usual time.
