Connector Design and Simulation

Connector designers are facing progressively higher frequency ranges, and so considerations such as cross talk, run time and signal integrity are becoming increasingly relevant. Complicated CAD models are commonly used and customers often require a connector's description by means of a SPICE replacement circuit. CST MICROWAVE STUDIO® (CST MWS) can easily accomplish this demanding task, allowing a full integration into the construction process.

3D EM Simulation in the Design Flow of High-Speed Multi-Pin Connectors

This article describes the design flow for a high speed connector using different simulation tools. The goal is to enable a first pass design without time-intensive and costly iteration steps. In addition to other simulation tools, CST MICROWAVE STUDIO® (CST MWS) is used during different stages of the design process to find fundamental design parameters and to predict the behaviour of a complete telecommunication system.

Signal integrity analysis and circuit extraction of a mounted SMA connector

A physically based method is used for estimating the equivalent circuit model of an SMA connector soldered on the top plane of a multi-layer board and connected to a single-end stripline. Starting from the scattering parameters (S-parameters) evaluated using a simulation software package, the equivalent circuit is extracted by modeling each part of the structure. The circuit is then validated by comparing the outputs obtained via circuit-level simulation of the extracted physical circuit with those computed by means of the full wave solution.

50 GHz End Launch Connector Test Boards

For many years Southwest Microwave has manufactured field replaceable connectors and launch accessories where connector performance was easily verified by measuring two connectors back-to-back as a two-port device. With the introduction and success of Southwest Microwave end launch connectors, the packaging responsibility has fallen to Southwest Microwave. To assure maximum performance of the Southwest Microwave end launch connectors, equally high performance test boards were needed to accurately measure the connectors. Read full article..
