Experimental circuit modeling of coupled interconnection structures based on causality

In this paper a time-frequency domain technique for the experimental circuit modeling of coupled two-port interconnection structures and discontinuities is presented. The technique models and de-embeds each appearing discontinuity and coupled substructure of the DUT one by one, and is based on the principle of causality. To validate the accuracy of the circuit models, measured reflection, transmission, near-end and far-end crosstalk are compared with simulated results.
