摘要

通过在延迟线中引入由周期性传输线不连续组成的滤波器，提高了s波段行波管的性能。滤波器被设计用来抑制二次谐波，二次谐波在这个管中特别强，特别是在低频时。主要目标，即提高电子速度谱在较低的工作频带，从而延长管的带宽，被证明。

Filter helix implementation into an S-band TWT design

The performance of an S-band traveling wave tube (TWT) is enhanced by introducing a filter consisting of periodic transmission line discontinuities into its delay line. The filter is designed to suppress the second harmonic which is particularly strong in this tube especially at low frequencies. The main goal, i.e. to improve the electron velocity spectrum at the lower operating band and, thus, to extend the bandwidth of the tube, is demonstrated.
