The band-reject filter based directional filter structure has been demonstrated as an effective way to achieve this goal. However, the prototype reported is cascading resonators in the lateral direction. When the order of the filer gets higher, the lateral cascading leads to rapid oscillation in the stop-band of S41 and a lengthy structure. This paper demonstrated a 4-pole band-reject filter based DF using direct-coupled band-reject filter. It achieves the highest order of DF response reported without the rapid oscillation in the stop-band. Yet it is about 30% smaller compared to previous 3-pole directional filter prototypes.","PeriodicalId":128968,"journal":{"name":"2013 IEEE MTT-S International Microwave Symposium Digest (MTT)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117055335","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}

Since the proposed resonator has the 2nd and 3rd harmonic suppression characteristics, the phase noise of the developed oscillator can be significantly improved about 10 dB at 100-kHz offset frequency as compared with that of the conventional one. To the best of our knowledge, this is the first paper to figure out the reason of this improvement using impulse sensitivity function (ISF). The calculated ISF parameters, c2 and c3, of the proposed configuration demonstrate that the noise portions contributed from the 2nd and 3rd harmonics are effectively reduced.","PeriodicalId":128968,"journal":{"name":"2013 IEEE MTT-S International Microwave Symposium Digest (MTT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124892937","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}

The key concept is to use resonator dimensions at higher frequencies and then apply capacitive loading to achieve the desired resonant frequency. The proposed technique was verified through experimental work of a third-order Chebyshev type bandpass filter centered at 1 GHz. Up to 80% reduction in overall area can be obtained when the unloaded resonator resonates at three times the desired operating frequency. In addition to the reduction in the overall area, an improved suppression of spurious harmonic responses was also achieved attributed to the higher operation frequency of the unloaded resonators.","PeriodicalId":128968,"journal":{"name":"2013 IEEE MTT-S International Microwave Symposium Digest (MTT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115570458","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}
