The push-push method has been used for designing the oscillator. Two identical double parallel coupling microstrip lines that are arranged at the output part are combined to block the DC power and are also used as band pass filters in order to suppress the fundamental frequency. By using a resistance at each feedback part to stable the DC point, the phase noise is improved. The output power of 3.60dBm at 19GHz, and the phase noise of -72.32dBc/Hz and -103.18dBc/Hz at the offset frequency of 10kHz and 100kHz are obtained, respectively.","PeriodicalId":314019,"journal":{"name":"2012 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123374501","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}

Symmetric transmission response and four transmission zeros (TZs) in the double-layer case are implemented based on substrate integrated waveguide (SIW) technology. An inset feeding is used to achieve the impedance matching, and location shift of the feeding lines has been adopted so as to acquire balanced responses. Two adjacent SIW cavities are coupled through a slot on the common ground plane. As a result, the proposed double-layer dual-mode SIW filter not only largely reduces the dimension, but also occupies a good out of band rejection performance.","PeriodicalId":314019,"journal":{"name":"2012 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129313620","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}
