Methodology to Model and Design Cost Effective Connectors for Radio Frequency application

摘要

Radio frequency connectors are used in industry to connect different types of cables, devices and systems. Connectors available, have variation in their design parameters, such as characteristics impedance, Voltage standing wave ratio (VSWR), power handling capability, shielding effectiveness and other characteristics to meet system requirements for different operating -frequencies. Physical structure and geometries of connectors also affects the frequency dependent design parameters. Thus every type of connector cannot be used for all user required operating frequencies. Design engineers have to make trade-offs between these design-parameters while selecting the most appropriate connector for their application. But they less frequently focus on the selection of appropriate connector to meet system requirements as these are equally critical in achieving system requirements. In this research we focus on the shielding effectiveness (SE) parameter. There are different test methods for SE measurement but we follow transfer impedance approach, which has the lowest cost of test system and moderate time required to obtain data. Following this approach we have devised the simplest method to find SE from scattering parameters.
