摘　　要：对新型回旋速调管放大器的链式群聚腔—TE模簇腔进行研究 ,通过三维电磁模拟对其进行分析和计算 ,讨论了损耗介质对群聚腔Q值的影响 ,以及内外腔耦合孔数量对谐振特性的影响 .模拟计算结果和冷测实验吻合得很好 .最后 ,为正在研制中的Ka波段三次谐波倍增回旋速调管放大器设计了一种链式群聚腔 .A novel chain bunching cavity of gyroklystron amplifier, which is the clustered-cavity with TE mode, is studied. Analysis and calculations have been done by using three-dimensional electromagnetic code. The effect of loss medium on Q factor of bunching cavity is discussed, and the influence of the number of coupling-holes on resonance characteristic is also analyzed. Simulation results are in good agreement with cold-test experiment. Finally, a chain bunching cavity is designed for the developing Ka-band frequency-tripling gyroklystron amplifier.
