前田敦子的轨迹 电影:帮忙翻译滤波器

Abstract
This article mostly introduced the theory and design means of microwave lowpass filter.from the definition of filter working principle and how to exert filter’s the best performance to micromave filter’ development history, working principle in network,basic configuration to the design of microstrip lowpass and the same axis cavity-body lowpass,this article all introduced.
On the back of the article,it thread actual manipulation,manage software APPCAD and Ansoft Designer progress imitating,lastly devise microstrip lowpass and the same axis cavity-body lowpass which meet the design need.
This article detailly explained lowpass filter’sdesign progress on actual engineering, needed theory knowledge and some software’s basal operateing course.
