Methods of connector S-parameter extraction depending on broadband measurements of symmetrical structures

Several methods to de-embed high-frequency two-port networks are figured out. In a first step, the scattering matrix S of a coaxial connector is determined. After the explanation of the measurement technique, two different methods of extracting the S parameter matrix will be presented and compared. Further objective of this elaboration is the comparison of the measured frequency responses of Rosenberger K and SMA connectors at frequencies up to 40 GHz. The ascertained data are essential for the possibility of replacing cost-intensive connectors by SMA, being an interesting option for growth sectors in radar technology such as automotive suppliers.
