摘　　要：本文针对宽带行波管(6~18GHz/200 W)中谐波指标的问题进行初步研究。应用谐波注入理论,通过在行波管输入端增加微波链路的方式,达到抑制宽带行波管二次谐波的目的。经过对微波链路的设计并进行带管试验,试验结果初步达到预期指标,在6~9GHz频率范围内,二次谐波抑制比基本小于-14.13dBc。Harmonic phenomenon in wide band TWTs（6-18 GHz/200 W）are researched.To suppressthe 2 nd harmonic in broadband TWTs,harmonic injection theory is applied and a microwave link is added to the input port.The designed microwave link is examined in TWT thermal test and the result can reach the design target.During the frequency range of 6-9 GHz,the harmonic suppression ratio is lower than-14.13 dBc.
