Traceable S-Parameter Measurements in Coaxial Transmission Lines up to 70GHz By Johannes Hoffmann
Paperback: $19.88
Ships in 3-5 business days
This thesis describes the computational process from dimensions and material parameters of coaxial standards to traceable S-parameters. Standards contain coaxial connectors and sections of... More > transmission line. Several models of the slotted coaxial connector and of rough coaxial transmission lines are discussed. The S-parameters of the standards are used to calibrate a vector network analyzer. For this purpose an overdetermined Bayesian calibration algorithm, which is described in this thesis, can be used. The calibration algorithm assumes imperfections in the definitions of the standards and in the calibration model of the vector network analyzer. Highly accurate and robust calibration is the result of the underlying statistical model. Finally, a technique to measure S-parameters in nonstandard coaxial connectors is described. It relies on the characterization of beadless adapters.< Less
