在一篇测量相关的应用文档中对S参数的表达是: “Scattering” or ‘s’ parameters are a measure of reflected power and transmitted power in a network as a function of frequency. The “Network” could be a coax cable, passive antenna, active amplifier, microwave filter, etc. S-parameters have ...
S-Parameter(Part I)SPARQ系列述评之三 ——关于S参数(上)汪进进 编写 Frankie.Wang@LeCroy.com 美国力科公司 无源网络如电阻，电感，电容，连接器，电缆，PCB线等在高频下会呈现射 频、微波方面的特性。S参数是表征无源网络特性的一种模型，在仿真中即用S 参数来代表无源网络，因此，S参数在射频、微波和信号...
Q: How to use VNA to measure the impedance of differentail Tx Line? Any suggestion for calibration method if freq. is over 5 GHz? A: You can use 4-port VNA to do a 4-port calibration and measurement on your Tx line, the 4-port single-ended S-parameters can be transformed by the...
