螺旋耦合型慢波结构,是近年发展起来的一种大功率正交场放大管慢波线。它具有较宽的带宽,较高的耦合阻抗,较大的平均功率容量,易于实现宽带传输匹配,因而获得了比较广泛的应用。本文采用多导体传输线及等效电路方法,对这类慢波结构进行了理论分析,导出了色散特性和耦合阻抗的解析表达式,计算了场的横向分布,运用大量的计算机结果,讨论了慢波结构各个尺寸对色散和耦合阻抗的影响。实验结果证明,本文所给出的结果可供工程设计使用。
Spiral-coupled slow-wave structure is developed in recent years, a high-power orthogonal field amplifier tube slow-wave line. It has a wider bandwidth, higher coupling impedance, larger average power capacity, easy to achieve broadband transmission matching, which has been more widely used. In this paper, multi-conductor transmission lines and equivalent circuit methods were used to analyze the structure of such slow-wave structures. The analytical expressions of dispersion characteristics and coupling impedances were deduced. The horizontal distribution of the field was calculated. Using a large number of computer results, Influence of Waveform Size on Dispersion and Coupling Impedance. Experimental results show that the results presented in this paper are available for engineering design.
