A model for bandpass nonlinearities based on Harmonic measurements
Paper in proceedings, 2003

This paper presents a model for a bandpass nonlinearity which is based on measurements on several harmonies of the output. The model has a quadrature structure, with a memoryless nonlinearity and a filter in each branch. structure can describe AM/AM as well as AM/PM conversions. The parameters of the nonlinearity and the filter are jointly optimized to fit the measurements. Analytic expressions for the parameters of the model is found by means of the MMSE optimization. The method is applied to find a model for a 60GHz solid-state power amplifier based on a set of measurements on different harmonics of the output.
