行波管在多倍频程带魔工作的基本特点,以及理论分析计算工作的探讨,在报告之一和报告之二中已有详细论述。本报告仅将研制高频系统中的部分实际工作作一小结。 高频系统是研制宽频带行波管的首要工作,只有在实际上解决了这个问题,才能进而从事管子的研制。高频系统包括信号的输入输出耦合装置和无色散的(忄万)波系统二个部分。讯号输入输出耦合装置要求它的驻波比在2以内,无色散(忄万)波系统要求频带范围达到1:4以上。这些要求,在我们的工作中已可达到。但是
The basic characteristics of traveling wave tube in multi-octave band magic work, as well as the theoretical analysis and calculation work, has been discussed in detail in the report one and the report two. This report only summarizes some of the actual work in the development of high-frequency systems. High-frequency system is the development of broadband traveling wave tube primary work, and only in fact solve this problem, in order to proceed in the development of the tube. High-frequency system includes the signal input and output coupling devices and dispersion-free (million) wave system in two parts. Signal input and output coupling device requires its VSWR within 2, without dispersion (忄 Wan) wave system requires the band to reach 1: 4 or more. These requirements have been achieved in our work. but
