摘要

摘要: 该文对Ka波段空间行波管宽频带、高线性、高效率的慢波系统进行设计，通过动态渐变技术实现了低相位失真、高效率的指标要求。在此设计基础上研制的Ka波段空间行波管实现了宽频带(25~27 GHz)、低非线性失真(非线性相移40 , AM/PM2.86/dB ，三阶交调10.39 dBc)、高效率(总效率51.7%)。经数传系统测试，误码pe优于10-6 的情况下C/N0有2.4 dB裕度，满足了卫星数传系统对多通道并行传输方案的工作需求。

Abstract: In this paper, the design of Ka-band broadband, high-linearity and high-efficiency slow-wave system is proposed for Space Traveling Wave Tube (TWT). The dynamic phase-shifting technique is used to achieve low phase distortion and high efficiency. Based on this design, the Ka-band TWT is developed to realize wideband (25~27 ), low nonlinear distortion (non-linear phase shift40, AM / PM2.86/dB, third order intermodulation10.39 dBc), high efficiency (total efficiency51.7%). By the digital transmission system test, the error codepe is better than10-6 in the case ofC/N0 2.4 dB margin, it meets the satellite data transmission system for multi-channel parallel transmission program work requirements.
