The device, designed for 85 to 105 GHz, is based on the interference pattern also known as self-imaging, which occurs due to a higher order mode propagation in a multimode waveguide. If the multimode waveguide is asymmetrically excited, a phase shift difference arises between two occurring field maxima. By placing LC in the region of one field maximum the phase shift can be adjusted by means of the tunable permittivity. This allows to control the interference pattern and therefore the position of the field maximum at the output of the multimode waveguide, where single mode DWs are connected. In the measurements, a port isolation of 40 dB at 94 GHz was achieved, while the other switching configuration shows a port isolation of 10 dB at 110 GHz. For both cases, the input reflection is below −15 dB over the whole frequency range.","PeriodicalId":6675,"journal":{"name":"2018 IEEE/MTT-S International Microwave Symposium - IMS","volume":"22 1","pages":"179-182"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80095484","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 co-design of these circuits enable a switchable bandstop filter that autonomously responds to an unexpected above-threshold interfering signal within its bandwidth in orders of magnitude less time than conventional switchable or tunable bandstop filters. In contrast to limiter circuits that are based on PIN diodes that are switched by RF power, the proposed autonomously-switchable bandstop filter has high linearity in all states. A third-order suspended-stripline prototype switchable bandstop filter with a second-order resonant power sensor was fabricated and measured to test the technique at 2.15 GHz.
