Title

De-Embedding Method to Accurately Measure High-Frequency Impedance of an O-Shape Spring Contact

Abstract

In this paper, a de-embedding method is proposed to measure the impedance of an innovative O-shape spring contact, for frequency up to 30 GHz. To allow the de-embedding method to be applied in practical situations, both conductor loss and the discontinuity associated with the junction are taken into account. Results obtained from the de-embedding method are validated using full wave simulation. In the simulation model, the O-shape spring contact is cut into two pieces based on the current flow paths, providing a straightforward way to understand why a resonance exists in the impedance profile of the connector. Lastly, the advantages and drawbacks of this method are discussed.
