摘　　要：针对短毫米波有源相控阵应用,文中优化设计了W波段高效率高频系统、低电压电子枪、一维阵列电子注平面聚焦系统和4路平面集成行波管拓扑结构,采用常规PPM聚焦系统制管验证了高频系统设计的有效性,设计并制作了2路流通管样件,电子注流通率均高于85%,验证了一维阵列电子注平面聚焦系统的设计有效性。基于验证的高频系统、低电压电子枪以及平面磁聚焦系统,设计了4路平面集成行波管拓扑结构,研制了W波段4路平面集成行波管样管。测试结果表明,4路行波管电子注流通率均高于80%,相同工作电压(12.6 kV)下4路行波管输出功率优于10 W,带宽均达到6 GHz,增益均高于25 dB,具有较好的电性能一致性,为短毫米波行波管有源相控阵应用提供了新的解决方案。For the application of short millimeter wave active phased array,W band high efficiency RF system,low voltage electron gun,1-D electron beam array planar focusing system and 4-channel planar integrated traveling wave tube(TWT)topology are optimized and designed in this paper.The effectiveness of the RF system design is verified by using the conventional PPM focusing system to make the tube.Two channel beamstick samples are designed and made,and the electron beam transport rate are higher than 85%,which verifies the effectiveness of the 1-D electron beam array planar focusing system.Based on the validated high efficiency RF system,low voltage electron gun and planar focusing system,the topological structure of 4-channel planar integrated TWT is designed,and the sample tube of W band 4-channel planar integrated TWT is developed,the test results show that the electron transport rate of the 4-channel TWTs is higher than 80%,the output power of the 4-channel TWTs is better than 10 W,the bandwidth is 6 GHz,and the gain is higher than 25 dB under the same working voltage,which has good electrical performance consistency and provides a new solution for the application of short millimeter wave TWT active phased array.
