Abstract

Abstract

The high-order mode coaxial cavity output circuit and the double-gap coupled cavity circuit are important for high frequency, high power and broadband klystrons. In this study, the two structures mentioned above are combined. The real part of the gap impedance of the filter-loaded double-gap output cavity is derived according to the equivalent circuit theory. In addition, the method for reducing the external quality factor of high-order mode double-gap output circuit is discussed on the basis of the microwave principle and simulation. The output circuit loaded with the designed filter has a bandwidth of 9.7%.
