摘要
本文讨论了行波管夹持杆微波性能的测试技术。采用模式识别技术,实现了在不同频段用同一测试腔对夹持杆介电参数的测量。研制的自动机械传动装置,解决了行波管夹持杆复介电常数沿轴向分布的测试问题。除行波管夹持杆外,研制的测试仪同样可用于其它类似杆状介质材料的测量。
A test technique of the microwave properties of the dielectric rod of the travelling wave tube is discussed. It has come true that the complex permittivity of the dielectric rod can be measured with a single cavity at the different frequency band by a technique of distinguishing modes. The problem to measure the distribution of the complex permittivity of the dielectric rod along its axial line has been solved with the automatic machinery driver. Meanwhile, the developed measurement instrument may be used for the measurement of the similar dielectric materials in the shape of rod besides the measurement of the dielectric rod of the travelling wave tube.
