The power-added efficiency is optimized by tuning the resonator position numbers, which map to resonant frequencies, without need for a load-pull characterization. Because no characterization is required, significant time savings in computation is expected, and tuning is expected to be more robust to drift and hysteresis of the tuner characteristics.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"129 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":"128427461","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}

Each resonant chamber of the presented filter consists of 25 individual resonant elements arranged in an interdigitated fashion along the circumference of three concentric rings. The resonator occupies a volume of 40 × 40 × 5 mm3 and has an unloaded quality factor of over 1800. The internal height of the filter (5 mm or 10.8°) is lowest reported in the literature. The measurements of the filter are in an excellent agreement with simulations — the measured insertion loss is 0.44 dB, while the theoretically predicted value stands at 0.37 dB.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"1 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":"130949179","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}
