Wideband Spice-compatible modeling of packages

An extraction method for automated generation of lumped-circuit models of multiport low-loss broadband devices is presented. The method takes a table of S-parameters of the modeled device as the input and translates it to a Spice-compatible netlist. This method differs from the existing ones in making a tight link to the physical properties of the modeled device observing and yet remaining versatile and highly automated. The extraction of the model parameters is based on the hybrid matrix because of its good numerical properties including the DC point. The RLC models incorporate all the major parasitic effects, including capacitive and inductive coupling, distributed effects, skin effect and dielectric relaxation.
