X波段多注速调管双间隙输出腔特性研究
|
摘要
针对X波段高功率多注速调管输出腔功率容量和对速调管效率的影响问题,通过仿真软件对单间隙和双间隙输出腔特性进行了仿真分析和设计优化,仿真分析结果表明,对于X波段速调管来说,与单间输出腔相比,双间隙输出腔可降低间隙场强约50%,提高特性阻抗R/Q值一倍以上,并可有效提高带宽约31.7%。通过对比双间隙输出腔的谐振频率、-3dB带宽、有载Qext值以及电场分布特性的仿真与测试结果,验证了仿真分析和设计方法的有效性,对X波段高功率多注速调管研究设计具有指导意义。
To investigate the power capacity of the X-band high power multi-beam klystron output cavity and the effect of the output cavity on the efficiency of the klystron,characteristics of single-gap and double-gap output cavitiesare simulated and optimized by using simulation software.The simulation analysis results show that for the X-band klystron,the double-gapoutput cavitycan reduce the gap field strength by 50%,increase the R/Qvalue by more than double,and increase the bandwidth by about 31.7%when compared with the single-gapone.The comparisonof the simulation and test results of the resonant frequency,the-3 dB bandwidth,the Qextvalue and theelectric field distribution characteristics of the double-gap output cavity indicates that the simulation analysis and design method are valid,and they have guiding significance for the research and design of X-band high power multi-beam klystrons.
