Effect of Contact Point Distribution to the High-Frequency Impedance on a Coaxial Connector

摘要

In this paper, we investigate an equivalent circuit for estimating connector contact failure, which saves computation resource significantly. The simulation results, validated by measurement, reveal that both the asymmetric contact distribution and fewer contact points increase the inductance on the connector. Using this lumped element circuit, different cable contact scenarios at the connection, i.e. the contact distribution and the number of contact points, can be simply simulated by changing the inductance term in the model.
