Radio-frequency connector and interconnect reliability in spaceborne applications

In addition to quality electronic components and subsystems, highly reliable interconnects are imperative in high-reliability applications such as spacecraft and satellites. System designers must therefore address and resolve issues related to the proper design and assembly process for connectors and interconnects for passive and active components. We have developed guidelines for the design of a space-qualifiable connector system based on our experience with defective hybrid couplers and power dividers, as well as our understanding of the material properties of the connector dielectric. We also discuss testing and the qualification of vendors of connectors and interconnects necessary to ensure high-reliability radio frequency and microwave components
