The designed filter consists of a crossed shape resonator in which tuning has been introduced using varactor diodes. The filter has been developed on a 60 mil thick laminate and characterized using Keysight Field-Fox analyzer N9918A. The characterized filter has a tunable center frequency from (3.43 - 3.88 GHz) with insertion loss less - 5 dB along with a tunable lower or upper band edge. The proposed reconfigurable filter will play an important role in the design and development of plasmonic circuits and systems.","PeriodicalId":6675,"journal":{"name":"2018 IEEE/MTT-S International Microwave Symposium - IMS","volume":"75 1","pages":"224-227"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89209225","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}

By using the principle of resonant hole coupling it becomes possible to assign two additional transmission zeros in the stopband of the filter. These extra transmission zeros are far away from the passband and allow to hold the attenuation level deeper than usually. Measurement results from the improved filter as well as results from a normal fully canonical filter with the same dimensions are presented for comparison.","PeriodicalId":6675,"journal":{"name":"2018 IEEE/MTT-S International Microwave Symposium - IMS","volume":"1 1","pages":"1245-1248"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83056517","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}

Presently the S-band radar allocation is highly coveted for spectrum sharing with wireless communications. To share the band with wireless systems, next-generation radar transmitters must be able to reconfigure in both frequency and spectrum usage in real time. We demonstrate S-band reconfigurability of a high-power tunable evanescent-mode cavity matching network capable of 90 $mathrm{w}$ of RF power handling. The system can switch between different operating frequencies, optimizing its power-added efficiency (PAE) while meeting simultaneous adjacent-channel power ratio (ACPR) constraints. This reconfiguration capability provides a useful building block for dynamic coexistence of a radar transmitter with other wireless systems in the S band.","PeriodicalId":6675,"journal":{"name":"2018 IEEE/MTT-S International Microwave Symposium - IMS","volume":"58 1","pages":"915-918"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84757047","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}

Dual-modes are excited orthogonally for miniaturization, which can be mutually coupled by the use of a cavity perturbation technique. Varactor diodes are used to tune cavity resonant frequencies independently since the arranged tuning units are only set for affecting one of the related modes. Combining controlled external coupling, all parametric tunings are achieved such as center frequency, bandwidth, transmission zero and other reconfigurable filtering characteristics. On the basis of tunable resonant frequencies, quasi-elliptical, linear phase and intrinsic-switching capability are obtained. For an experimental validation of the proposed structure, a dual-mode bandpass filter was fabricated and measured. As one example of the quasi-elliptical response, a constant absolute bandwidth of 200 MHz in the tuning range 2.83–3.55 GHz with insertion loss of 1.76–5.08 dB is observed in our experiments.","PeriodicalId":6675,"journal":{"name":"2018 IEEE/MTT-S International Microwave Symposium - IMS","volume":"1 1","pages":"397-400"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88659416","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 use of the new L5 signal can improve the accuracy and reliability of the typical mass-market receivers that rely only on the L1 signal. The proposed architecture is based on a compact microstrip diplexer that separates the two bands of interest providing the necessary filtering. Each band is down-converted independently and then both are combined at intermediate frequency (IF) in order to obtain one analog output. This front-end architecture is suitable for implementing a programmable high accuracy GPS receiver using a generic digital signal processing platform. The current work focuses on the diplexer design as well as the selection of the sampling rate and frequency plan required to avoid band overlapping before and after the analog to digital conversion. Satisfactory measurement results of the diplexer are presented.","PeriodicalId":6675,"journal":{"name":"2018 IEEE/MTT-S International Microwave Symposium - IMS","volume":"22 1","pages":"995-998"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87179576","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}
