A参量在高频阻抗测量中的应用

 根据微波网络理论提出了利用A参量求解高频阻抗的新方法,并将其应用于网络分析仪系统,对短波阻抗进行了测量。实践证明,该方法与传统的利用S参量的方法(利用反射系数)相比大大地拓宽了阻抗测量范围,在通用仪器上获得了比专用仪器高的测量精度,同时还解决了网络分析仪与非同轴网络的连接问题。

THE APPLICATION OF 'A' PARAMETER ON HIGH FREQUENCIES IMPEDANCE MEASUREMENTS

This paper presents a new method to calculate HF impedance with 'A' parameter . which is derived from the theory microwave network. and that method is applied to the network analyzer system to do short wave impedance measurements. It turns out by practice that the method not only expands the range of impedance measurements greatly. hut also can get higher accuracy of measurements on the common instruments than on the special instrument with the conventional 'S' parameter method . With this method the problem of connection of metwork analyzer and non-coaxial network is solved.
