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。
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.
