本文研究了低功率和高功率的高效率行波管放大器的一般设计方法。此设计方法的依据是从大信号曲线中选择设计参数C、QC、B和b的最佳值(得到高效率),以及设计这样一种放大器,它应有特定的高频结构能满足功率和频宽要求并有尽可能接近最佳值的工作参数.在最佳设计参数不可能全部同时实现的情况下,设计师可选择他所希望调到的参数。此设计方法首先应用于螺旋线式管中,而后推导出了校正因数,这些校正因数能根据同样的一组曲线设计任何类型高频结构的放大器。
This paper studies the general design method of high efficiency TWT amplifier with low power and high power. The basis for this design approach is to choose the best values of the design parameters C, QC, B, and b (resulting in high efficiency) from the large signal curve and to design an amplifier that should have a specific high frequency structure that satisfies both power and Bandwidth requirements and operating parameters that are as close as possible to the best possible value.When the best design parameters can not all be achieved at the same time, the designer can choose the parameters he wishes to tune in. This design method first applies to helical tubes and then derives correction factors that enable the design of amplifiers of any type of high-frequency structure based on the same set of curves.
