The proposed tunable filter is designed and fabricated with the constant ratio rule in which the capacitances of the each stage maintains a constant ratio without any dependency on the miniaturized electrical length. As a result, the filter can be tuned with the reserved equivalent condition using a single control voltage. To show the validity of the proposed method, a third-order 0.5 dB ripple Chebyshev filter with a center frequency of 900 MHz and a fractional bandwidth(FBW) of 10% was designed and fabricated. The measured center frequency of the fabricated filter is changed from 606 MHz to 944 MHz, 338 MHz with the single control voltage from 0.5 V to 4 V. Expect of slight change of the bandwidth, the measured filter characteristics are well reserved with the various control voltage.","PeriodicalId":257679,"journal":{"name":"2008 IEEE MTT-S International Microwave Workshop Series on Art of Miniaturizing RF and Microwave Passive Components","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115657760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new feed arrangement for the miniature dual-mode filters is also proposed and investigated in detail. The feed arrangement supports the proposed enhanced coupling between I/O ports of the filter. Both calculated and measured results for two-pole and four-pole dual-mode filters are presented.","PeriodicalId":257679,"journal":{"name":"2008 IEEE MTT-S International Microwave Workshop Series on Art of Miniaturizing RF and Microwave Passive Components","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121657222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
