Measurement and modelling of nonlinear systems at microwave frequencies.

Project Details


The current trend in the telecommunication applications is to provide an ever increasing bandwisth at the cost of an ever decreasing power consumption. Thois imposes high accuracy characterisation of the (nonlinear) behaviour of the components and systems involved. Till now, the microwave components were mainly characterised using the linear S-parameter representations (mostly extracted out of measurements) or non-linear spice models based on the knowledge of a model structure and/or intrinsic material constants. The main goal of this research is to develop measurement methods and instrumentation that is capable to measure the non-linear behaviour accuratly. Starting with these results, behavioural models for this behaviour will then be extracted. Care will be taken during this modelling phase to obtain models that are both accurate and numerically cheap to evaluate.
