怎么做滤波器?
录入:edatop.com 点击:
本人可以说是完全的新手,射频电路知识也少的可怜,但是作业有时间限制,所以论坛求助,只希望从中学到东西。
作业是根据英文文献做滤波器。(俺的英文也不太好)
论文标题是《Implementation of Compact UWB Bandpass Filter With a Notch-Band》,用ADS仿真,ADS也是现学的。
The initial UWB BPF consists of two distinctive parts, i.e.,stubs-loaded multiple-mode resonator(MMR) at the center section and two identical interdigital coupled-lines at the left and right sections.This MMR is formed by attaching three pairs of stepped-impedance stubs in the middle section.
In this sections, the interdigital coupled lines are re-arranged by lengthening and folding one of two coupling arms associated with the feed lines, resulting to create a notch-band at 5.6GHz within the UWB passband.
我希望各位前辈,高手,指点我,这个滤波器ADS原理图是怎么样,是用哪些元件?

网友回复:
这个滤波器的原理大概是利用中间的上下共6个高低阻抗线枝节实现一个超宽带的相应
然后用两边3线耦合产生的强耦合使超宽带带内达到合适的插损和反射。
原理图你可以查查MMR的原理和3线耦合的原理。

这是
南洋理工 祝磊老师的文章吧

挺复杂的一个滤波器,你可以先从最基本的高低带通滤波器开始,慢慢看这些英文文献,我研二的,呵呵一点建议
申明:网友回复良莠不齐,仅供参考。如需专业帮助,请学习易迪拓培训专家讲授的ADS视频培训课程。
