本文研究怎样制做C～J波段(0.5～20千兆赫)、多个倍频程的大功率(1千瓦)宽频带功率放大器系列。作者对目前生产的5000个左右各类型的超高频器件作了调研,认为只有螺旋线行波管的并联使用才能给出令人满意的性能。文中分析了并联使用中的问题。随后着重讨论了宽带运用中的相互调制、截获效应和器件设计的关系。对相移补偿问题的解决也作了分析。作者还对电源、占空比、价格、冷却等工业上实际问题做了讨论。本译文从器件的角度出发,对全文作了取舍整理,关心这些删缩处的读者可查原文。
This article studies how to make a series of high-power (1 kW) broadband power amplifiers in the C-J band (0.5-20 GHz) with multiple octaves. The author of the current production of about 5000 various types of UHF devices were investigated, that only the parallel use of the spiral traveling wave tube to give satisfactory performance. The article analyzes the problems in parallel use. After that, we focused on the relationship between intermodulation, interception and device design in broadband applications. The solution to the phase shift compensation problem is also analyzed. The author also discussed the practical industrial issues such as power supply, duty cycle, price and cooling. The translation from the device point of view, made the entire text of the trade-offs, care about these deleted at the reader can check the original text.
