A two level transient analysis of a circuit containing transmission lines modeled by segments of lumped elements

In this study, a computer-aided broadband matching technique based on the parametric representation of scattering parameters is proposed. The new technique combines the advantageous of the so called parametric approach utilizing the impedance formalism and the real frequency scattering technique. With the reformulation of these real frequency techniques, some laborious numerical computational steps are omitted. The descriptive network functions are obtained in an explicit form without any need for the polynomial factorizations and the solution of equation sets. The application of the technique and the comparison of the results with those of the other real frequency approaches is discussed with examples
