English abstract:
The X-parameter model is designed for modelling weakly nonlinear devices in an approximately impedance-matched invironment. Load dependent X-parameter models were proposed to overcome this, practically very relevant, limitation and model a nonlinear device in a highly mismatched environment. However, the applicability of load dependent X-parameter models for DUTs operation in deep saturation like in power amplifier design is questionable. This work evaluates the possibilities of using a load dependent X-parameter model in power amplifier design by comparing the results of a model build from mearsurements of a GaN-HEMT to in-situ measurements of the same device.
