Varactor diodes in a back-to-back configuration have been used to tune the filter response in terms of center frequency, bandwidth (BW) and return loss (RL) level. The proposed approach presents a high design flexibility in a very compact size, allowing us to prove both tunable BW and constant absolute BW over a tuning range of about 15% at C-band. As a validation example, a single dual-mode coaxial SIW resonator with 10 varactor diodes is used to implement a 2-pole tunable bandpass filter (BPF) with two transmission zeros (TZs) that has been designed, fabricated and tested. The filter has a fractional BW (FBW) range and insertion loss (IL) better than 100% and 5 dB, respectively, over the entire tuning range.","PeriodicalId":6720,"journal":{"name":"2019 IEEE MTT-S International Microwave Symposium (IMS)","volume":"34 1","pages":"17-20"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81713263","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}

A six-layer micro-fabrication process is developed to fabricate the T-type switch. PCM RF series switches are used to route the signal through various RF sections including 90-degree bends and a cross-over junction. The measured results for the proposed T-type switches demonstrate excellent RF performance of less than 0.6 dB insertion loss, better than 20 dB return loss and higher than 20 dB isolation in all states from DC to 67 GHz.

These are H2, second order intermodulation products (IMD2), for the case where a jamming signal is set to low frequencies (IMD2-Low) and when the jamming signal is set to high frequencies (IMD2-High).

However, the large number of phase shifters in conventional phased array architecture significantly increases the cost and system complexity, which brings it challenges in commercial use. In this article, we propose an innovative phase shifting architecture by mixing two travelling waves rather than using phase shifters. The phases of the antenna elements can be by simply changed by tuning the frequencies of the input waves, while the frequency of radiated signal is kept as constant. A 1 by 8 linear array based on the proposed technique is fabricated and tested.

Traditionally this has been limited by the pitch of SMA cables. When trying to go beyond this approach there are two problems to address. The first is outfitting a dilution refrigerator with enough lines to run from room temperature to the base temperature stage. The second is building a package for a quantum integrated circuit that houses enough microwave lines itself. We propose a solution to both of these problems by using RF flexible circuits to increase signal density in the dilution refrigerator and package while maintaining signal integrity. We also discuss the thermal, mechanical and RF considerations that go into designing such a system. Finally we show a proof-of-concept integration of the entire system including measurements with superconducting qubits.","PeriodicalId":6720,"journal":{"name":"2019 IEEE MTT-S International Microwave Symposium (IMS)","volume":"31 1","pages":"271-274"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88981031","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}
