摘　　要：本文介绍了国内外Q波段螺旋线行波管研究进展,给出了作者在Q波段螺旋线行波管设计和性能测试结果。电子枪采用皮尔斯型电子枪,高频采用螺旋线结构,为了提高行波管效率,采用四级降压收集极。测试结果表明在工作频带内连续波饱和输出功率超过30 W,总效率超过21%,行波管动态流通率超过98%,饱和增益超过了45.5dB。This paper describes the development of Q-band helix TWTs. The design and the experi- ment of a Q-band 30 W helix TWT in Beijing Vacuum Electronics Research Institute are introduced. Pierce gun and helix slow-wave structure are used in the TWT. In order to get higher efficiency, four-stage de- pression collector is adopted in the tube. The test results indicate that the saturation output power of the tube is more than 30 W, the efficiency is more than 21%, the gain is more than 45.5 dB and the beam transmission is more than 98%.
