摘要: 在新型L波段多注速调管的研制中，为了降低电磁聚焦系统的设计难度，需要减小输出波导的截面尺寸。为此，提出了在速调管输出组件中应用脊波导的方案。针对该型速调管的要求，设计了完整的脊波导输出组件并进行验证。计算结果表明，这种采用了脊波导的速调管输出组件，能够在10％的带宽内达到1.2以下的驻波比，理论功率容量达到490 MW。采用了该方案的组件尺寸紧凑，加工方便，调试容易。Abstract: In the development of a new L band klystron, in order to reduce the size, weight and power waste of magnetic focusing system, the size of output waveguide should be reduced. To solve this problem, a ridge waveguide was used in the output circuit. To validate this method, a ridge waveguide output circuit was designed and tested. The circuit’s voltage standing wave ratio is under 1.2 within 10% band width and theoretical power capacity is 490 MW.The output circuit with a ridge waveguide is compact and easy to make and test,and it has been used in the L band klystron．
