| Abstract: | The current development of electrical tunable band-pass filters and its application to the cosite interference is presented in this paper.The configuration of the electrical tunable band-pass filter is optimized based on the pseudo-combline,and the improved filter is tuned with capacitors at both the two ends of the filter.The analytical solutions of the parameters and the design procedure of the filter are presented.The filter designed in this work is tuned from 580~900 MHz,and gets some advantages in the dimension. |
