S parameter causality check
Web24. nov 2024 · The S-parameter matrix can be used to determine reflection coefficients and transmission gains from both sides of a two port network. This concept can further be used to determine s-parameters of a multi port network. These concepts can further be used in determining Gain, Return loss, VSWR and Insertion Loss. http://www.spisim.com/blog/s-param-quality-checklist/
