| Abstract: |
| This paper presents the method of precise design for Microwave band-pass filter by using advanced EDA simulation tool.According to the technical characteristics of filter,the type,structure and optional series can be decided.Then the stopband rejection and insertion loss can be estimated.By means of structure simulation and optimization for physical size,the minimal loss,inband ripple and prefect stopband rejection can be achieved,which has been proved by the design result. |
