摘　　要：本文介绍中国科学院电子学研究所研制成功的相对带宽8%的C波段宽带多注速调管。C波段宽带多注速调管KC4137和KC4148在100 kW和160 kW功率电平上,获得了相对带宽8.1%和8.5%,相应的最低效率为29%和32.5%,平均功率为5 kW和8 kW。论文分析了由双间隙输出腔引起的杂谱(寄生输出),讨论了抑制杂谱的方法。The research progress on C-band broadband multi-beam klystron at Institute of Electronics,Chinese Academy of Sciences（IECAS） was presented in this paper.The relative bandwidth of 8.1% and 8.5% for C-band broadband MBKs KC4137 and KC 4148 were obtained on the power level of 100 kW and 160 kW with efficiency of 29% and 32.5%.The parasitic output caused by high order mode of double-gap output cavity was analysis,and the method for suppressing it was discussed.
