摘要

本文介绍了宽带相互作用和谐波抑制的研究。得到了一种用于宽带行波管(TWT)的特殊色散形状。对负色散进行了研究和仿真。在此基础上，设计了用于微波功率模块(MPM)的宽带行波管。与原有的平色散行波管相比，负色散行波管的二次谐波含量降低了约10 dB，低频基频效率提高了约5%。制作了改进的行波管，仿真结果与实测结果吻合较好。

Simulation study on dispersion shaping and harmonic suppression in traveling-wave tubes

This paper describes the investigation of broadband interaction and harmonic suppression. A special dispersion shape used in broadband traveling-wave tubes (TWT) is obtained. The and simulation studies of negative dispersion are presented. On the basis of these studies, a broadband TWT used in microwave power module (MPM) is designed. Compared with the old TWT with flat dispersion, the new one with negative dispersion decreases the second harmonic content about 10 dB and improves the fundamental efficiency about 5% at the low end of the band. The modified TWT is fabricated and the simulation results meet the measurements very well.
