The broad curve could withstand input power of up to 41 dBm compared to 32 dBm and 29 dBm for the intermediate and narrow curves respectively.

Two circuit implementation techniques are employed: π-type reflection loads and folded Lange coupler. The π-type reflection loads and the folded Lange coupler are utilized in one stage reflection-type phase shifter to cover more than 180° phase tuning. Cascade of two stage RTPS is adopted to achieve 360° phase tuning. Measurements show signal losses of 6.4dB±1.4dB including pad loss, low gain deviation of 0.8 dB, and a 360° continuously tunable range across 11~13 GHz with 0-mW dc power consumption. To the best of our knowledge, the proposed phase shifter has the highest FOM of 46.2(°/dB), among all reported 360° X-band CMOS phase shifters.","PeriodicalId":243164,"journal":{"name":"2012 7th European Microwave Integrated Circuit Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128059082","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 fundamental resonance frequency and higher order resonant harmonics of the considered SLR are established. It is found that the first spurious resonance frequency can be conveniently controlled. For a proof-of-concept, a three-pole filter designed at 1 GHz, with a 6 % fractional bandwidth is fabricated and measured. A measured 2.3-dB insertion loss is achieved, with a first spurious passband located at four times the working frequency, i.e. 4 Ghz. Then, a U “corner” structure is considered to create a transmission zero at the upper stopband close to the high cut-off frequency leading to a deeper stopband rejection. Measurement and simulation results are in good agreement, thus validating the new concepts developed in this paper.","PeriodicalId":243164,"journal":{"name":"2012 7th European Microwave Integrated Circuit Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122739114","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}
