| 摘 要： | 根据行波管内微波信号在输能装置和切断衰减器处两个不连续性之间来回反射的物理现象，建立行波管输出段的简易网络串模型，并对行波管输出段传输特性参数的幅频特性、相频特性进行计算分析。结果表明：输能装置和切断衰减器的不连续性是造成幅相一致性行波管相位不可补偿的重要因素之一。

| Abstract: | The paper brings forward a serial network model of the mismatches in traveling wave tube (TWT) based on the physical phenomenon that microwave signal reflects between the two microwave mismatches at the output termination and attenuator of TWT. The effect of the two mismatches on the phase coincidence and amplitude coincidence of TWT is analyzed. The analysis indicates that the mismatches can lead to the possibility that the phase of phase coincidence TWT can't be compensated. It is necessary to measure the two mismatehes of TWT and combine with the production technique so as to reduce the reflections and improve the production quality of phase coincidence TWT. |
