在波导扫频测试系统中,波导定向耦合器的主要技术指标是高方向性和耦合平稳度,在结构长度上并不认真考究.但在较长波长的频段,由于波导尺寸及其单位长度重量变得越来越大,使原材料消耗和加工难度显著增加.缩短耦合器结构长度的必要性和经济性就成为一个不可忽视的重要问题.以我们研制的十公分波导耦合器为例,通过采取措施,其长度从1.6米缩短为1.17米,重量从12kg 减轻到9.1kg.而且减轻了工人劳动强度,节约了加工工时,方便了使用
In the waveguide sweep test system, the main technical specifications of the waveguide directional coupler are high directivity and coupling flatness, which are not carefully studied in the structure length, but in the longer wavelength band, due to the size of the waveguide and its unit weight Become larger and larger, so that the consumption of raw materials and processing significantly increased the difficulty of shortening the length of the coupler structure of the necessity and economy has become an important issue can not be ignored.With our 10 cm waveguide coupler as an example, by taking Measures, its length from 1.6 meters shortened to 1.17 meters, weight reduced from 12kg to 9.1kg. And reduce the labor intensity of workers, saving the processing time and ease of use
