【摘要】 行波管较大的横向尺寸限制了其在相控阵系统中的应用。针对此问题，对X/Ku波段大功率行波管的电子枪、收集极耐压及周期永磁聚焦(Periodic Permanent Magnet, PPM)系统两个关键部分进行小型化设计。通过采用复合管壳技术，解决了小型化PPM系统导致的电子注聚焦难题，将行波管高度缩减至20 mm以内，并实现了基于该行波管的微波功率模块集成。更多还原

【Abstract】 The large horizontal dimensions of traveling wave tubes(TWTs) have long been significant factors limiting their application in active phased array radar. This article elaborates on two key design of high-power X/Ku-band TWTs: the voltage resistance capability design of electron gun and collector, and the miniaturization design of periodic permanent magnet(PPM) focusing system. The focusing challenge of electron beams caused by the miniaturized PPM system is addressed through composite tube shell technology. The height of the improved TWT is reduced to within 20mm, and the microwave power module integration based on this TWT is achieved.更多还原
