摘要: In this paper, a novel miniaturization method for filter implementation is presented and validated. According to frequency response transformation, the structure has wideband bandpass in required band which lower than operation frequency. The in-band out-of-band characteristics are also improved realize wide passband stopband responses. For demonstration, three filters designed based on proposed ideas. efficient circuit area reduced by 56.8%-64.7% compared with conventional filter, indicating significant using method. Another advantage of our work that extended more 9f0 other structures. Good agreement between simulation experiment obtained.
