一、前言用于地球资源卫星地面站和微波治癌机的P波段平板三极管6018输出连续波功率1千瓦。设计当初,由于考虑采用钨钙镍镀铼作底金属的氧化物阴极等新工艺新技术,管子的结构尺寸比较小(管子最大直径为51.5毫米,总高度67毫米,阴极面积仅2.56厘米~2)。在研制中由于客观条件所限,未能实现这些新技术。在不更改管子设计和结构的前提下,为了要给出
I. INTRODUCTION The 6018 P-band flat-panel transistor for Earth Resources satellite ground station and microwave cancer treatment machine outputs 1 kilowatt of continuous wave power. At the beginning of the design, due to the consideration of the new technology and new technology such as tungsten-calcium-nickel-rhenium as the base metal oxide cathode, the structure size of the tube is relatively small (the maximum diameter of the tube is 51.5 mm, the total height is 67 mm, the cathode area is only 2.56 cm 2 ). In the development due to the objective conditions are limited, failed to achieve these new technologies. In the premise of not changing the pipe design and structure, in order to give
