Spirally shielded twinaxial cable assemblies are extensively used in multi-gigabit-per-second digital telecommunications systems. Unlike ideally shielded Twinaxial cables, spirally shielded cables exhibit resonant behavior which limits system throughput.

This body of work illustrates a predictive method for determining resonant behavior in twinaxial cables through physical measurement of commercially available cables and analogous transmission line fixtures, full-wave and quasi-static simulations, and equivalent circuit analysis.

It will be shown that frequency dependent standing wave resonances in twinaxial cables are independent of cable length and dependent on cross-sectional feature sizes, dielectric properties, and spiral shield pitch.
