Abstract
This paper focuses on behavioral modelling of passive RF blocks from frequency domain samples. This model has been implemented in Scilab/Scicos software which allows the resolution of implicit equations, therefore the implementation of bilateral behavioral models. This approach combines on one hand, the vectorfitting (VF) method which estimates the poles and residues of MIMO system, and the inverse Laplace transform on the other hand. The domain response S ij (t) varying with time is then evaluated. This method has been validated in the case of simple circuit (load) and generalized to MIMO system such as a power combiner. Thus, implementation of topological model of HPA is now possible
