Abstract

We developed an interconnect characterization procedure that first embeds the interconnect into the error boxes of a multiline thru-reflect-line calibration and subsequently de-embeds the interconnect with a multi-tiered calibration. We experimentally validated our method with distributed contactless interconnects in the form of broadside coupled coplanar waveguides as a test case. We find excellent agreement between experiment, full-wave simulations, and a distributed model of contactless interconnects. This work provides a rigorous method to accurately characterize interconnects when conventional approaches are not applicable.
