| Abstract: | Spurious response suppression is one of the most important factors for the microstrip filter.An effective design method is proposed to suppress the spurious response in a wide range of frequency.A prototype filter with adequate suppression from 2f0 to 3f0,is achieved by simulating and optimizing the combination of the bandpass filter and lowpass filter.This paper presents the foundation theories about microstrip filter and detailed design procedures using ADS and Ansoft Designer.The measured results show th... |
