Precise Characterization of Multipin Connectors
Abstract: Connectors are an integral part of any electronic system, allowing multiple parts of one system to
interconnect. However, they represent a discontinuity, and this discontinuity causes reflections,
differential-to-common-mode conversion and radiation. All these phenomena are more intense at
higher frequencies and they can significantly distort the transmitted signal which leads to the
reduction of transmission speed/bitrate.
Prediction of these effects using simulation requires a precise model of the connector with well defined
geometry and materials. The electrical properties of materials are often known up to a
certain degree of accuracy, therefore measurement is used for characterization or/and
verification. However, measuring such connectors with a Vector Network Analyzer requires the
connector to be mounted to a test fixture. In reality these fixtures have parasitic properties, which
can be comparable to properties of the connector itself. Measured S-parameters thus contain a
mixture of connector properties and fixture parasitics.
This presentation will demonstrate a technique for the extraction of the connector model from
measured S-parameters mitigating the effects of the test-fixture using CST STUDIO SUITE®.
The concept will be demonstrated on the example of a connector for automotive applications.
Biography: Enow Tanjong is currently a Senior Application Engineer with CST of America now part of
Dassault Systèmes Simulia where he serves a lead technical role in supporting pre-sales efforts in
the South-west region of the USA. He joined CST of America in 2006 as an Application
Engineer after receiving a B.Sc. Magna and M.Sc. in Electrical Engineering from the University
of Massachusetts. His graduate studies involved the numerical and experimental electromagnetic
analysis (modeling) of complex metallic radiating structures.
