摘要
微波技术基础教学实验系统单元模块的设计中,要求将单元模块信号通过连接器引出进行演示实验,而连接器过孔的引入会对实验指标产生较大的影响。该文以平行线耦合器为例,通过对比设计好的耦合器加入过孔前后的指标,证明了这一点。然后通过对过孔各参数进行调谐,找到了对指标影响最大的过孔参数。最后通过平行线耦合器与过孔联合设计,得到了较好的实验指标,保证了单元模块的演示实验效果。
In the design of the unit module of the microwave technology basic teachinig experiment system.It is required that the unit module signal be led out through the connector for demonstration experiment,and the introduction of the connector via hole will have a great impact on the experimental index.In this paper,the parallel line coupler is taken as an example to prove this point by comparing the index before and after vias is added to the designed coupler.Then,by tuning the parameters of the vias,the via parameter that have the greatest influence on the index is found.Finally,through the joint design of the parallel line coupler and the via,a good experimental index is obtained,which ensures the demonstration effect of the unit module.
