【摘要】 对Ka波段耦合腔行波管慢波结构的冷特性、注波互作用进行分析。设计计算出慢波系统的色散特性和耦合阻抗,利用大信号程序得到同步电压和等激励输入功率,最终获得高于300 W的输出功率。并结合实际测试情况,对比实际热测数据与仿真结果,在工作频带内两者数据较为符合,从而对大信号程序进行验证,同时为工程制管提供一定的参考。更多还原

【Abstract】 The cold-test parameters and beam-wave interaction of Ka-band coupled-cavity traveling wave tube(CCTWT) are analyzed in this paper.The dispersion characteristics and coupling impedance of the slow-wave system are calculated,the simultaneous voltage and encourage input power are obtained with large signal code,results of simulations show that the tube can generate more than 300 W of output power.Combining the results of experiment data,through the between the simulation results and experiment data,we test large signal code,and this also provide experience in the engineering design of CCTWT.更多还原
