本文陈述在大信号电平下调制电子注与行波管线路波再同步的方法。应用这类方法,特别当应用慢波线路的速度渐变和电压跳变技术时,有可能使各类行波管的效率达到50％到60％,这些方法的设计是比较严格的,要求大信号计算机分析。已在X和C波段5～10千瓦功率的线包聚焦耦合腔管子以及S波段30瓦功率电平、适用于空间通讯的螺旋线行波管中应用。

This article describes a method of resynchronization of modulated electronic notes and TWT line waves at large signal levels. The application of these methods, especially when using the slow-line speed-gradient and voltage-hopping techniques, makes it possible to achieve 50% to 60% efficiency for all types of traveling-wave tubes. The design of these methods is more stringent and requires a large signal Computer analysis Has been in the X and C band 5 to 10 kilowatts power line focusing coupling cavity tube and 30 watts of S-band power level for space communications spiral traveling wave tube applications.
