摘　　要：在以10腔旭日结构为方案的可调谐相对论磁控管中,分析了热腔下对磁控管性能有重要影响的零模成分与模式隔离因素,结合零模成分的形成原因以及轴向频率分量对调谐范围的影响,提出了调整大、小腔等效阻抗和体积,开放阳极端面,从而减小零模分量及增加调谐带宽的措施。CST模拟表明,通过这些优化,可调谐相对论磁控管的调谐带宽从最初的380 MHz提高到900 MHz。This paper focuses on two factors of 0-harmonic component and modes interval in frequency-agile relativistic magnetron under thermal cavity condition by way of example of 10 cavites rising-sun magnetron. Based on the analysis of these factors, it suggests to optimize the tunable bandwidth by balancing the effective impedance, adjusting the cavity and opening the anode port face, and reduce 0-harmonic component. The simulation result shows that the frequency-agile range increases from 380 MHz to 900 MHz after using the above mentioned methods.
