Application of Impedance Matching Circuit in Filter Measure
为解决扫频仪日趋老化带来的某型非标准阻抗滤波器测试问题，通过设计阻抗转换器实现了用网络分析仪对滤波器的测试。介绍了扫频仪与网络分析仪的测试原理和它们之间的区别，阐述了网络分析仪HPE5100B替代扫频仪JW1252W测试滤波器的实现方法，以及阻抗匹配电路的原理及其在滤波器测试中的应用。实验证明，用网络测试仪测试数值一致性好、操作简单、精度高、减少了工作量、降低了成本。
To solve the problem of some type nonstandard impedance filter measure owing to sweep generator＇s aging, an impedance matching circuit is designed to measure filters by network analyzer. In this paper, measuring principles of sweep generator and network analyzer are introduced as well as their differences. The implement of net- work analyzer HP E5100B instead of sweep generator JW1252W in filter measure is given, and the principles of impedance matching circ…查看全部>>
