| 摘 要： | 本文对超宽带50 W电子战超小型行波管设计进行了介绍,其主要技术难点为超宽带设计及超小型设计。通过设计行波管高效率慢波互作用系统来进行超宽带设计,使得行波管工作频带覆盖4～18 GHz,全频带(除低端边频4～5 GHz外)输出功率典型值为50 W,其中4～5 GHz频带内输出功率达到35 W,整管效率高于33%。在保障电性能的同时,通过降低工作电压实现整管各部件微型化设计,实现整管结构尺寸的大幅度压缩,实现了功率密度的大幅度提升,突破了小型化电子战整机系统安装空间的限制,适应了更高标准的电子战应用要求。

| Abstract: | A subminiaturized 50 W ultra-wideband traveling wave tube(TWT) for electronic countermeasure is proposed. The prime technical difficulties are the ultra-wideband design and the sub-miniaturization design. With a high efficiency slow-wave interaction system, the output power of the TWT reaches 50 W in 5~18 GHz and 35 W in 4~5 GHz, with the overall efficiency greater than 33% in the full band of 4~18 GHz. With guaranteed electrical performance, by lowering the operating voltage, the sub-miniaturization design of components is realized, the large-scale compression of TWT structure is achieved, and the power density is remarkably improved. The installation space limitation of miniaturized electronic countermeasure(ECM) systems is broken through, which gets well-adapted to higher requirement of ECM in the future. |
