A Quasi-TEM propagation mode has been assumed for developing the equivalent electrical model. Based on the geometries and definition of the back end of line, the model is capable of fully predict the behavior of the SCPS without any fitting parameters. The model was validated with measurements of S-CPS implemented in the 0.35-μm CMOS AMS technology. A good agreement is achieved between the model and measurements in a wide band (DC-40GHz). This model provides the designer a powerful tool for fast design of differential circuits, for which the use of S-CPS instead of microstrip lines can be very efficient.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"12 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83480894","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 tag is designed based on an open-ended slot structure and fed by a primary radiator from the middle. Feeding the antenna using coupling mechanism by a primary radiator results to lower fabrication complexity and costs as well as mechanical durability against continuous vibrations, humidity, water and mud. The whole tag is 0.084λ×0.066λ and can be read up to 5 m in the US band and 3 m in the EU band. By utilization of low cost FR4 substrate alongside the magnetically coupled primary radiator the fabrication costs diminishes significantly. An open-ended slot fed from the middle with bent T-shape pattern for the closed-end and meandered pattern for the open-ended side acts as the antenna and matching circuit together. The measurement results prove the functionality of the designed tag.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"69 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86674960","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}

However, one of the bottlenecks is how to mediate the self-interference (SI) between the transmitter (Tx) and the receiver (Rx). In this paper, a novel passive microwave device called Coupled-resonator Decoupling Network (CRDN) is proposed. A prototype CRDN is built and tested for proof-of-concept, where the four-port device consists of two inter-coupled lines of coupled resonators. The SI is suppressed from -17 dB to below -41 dB within a frequency range of 50 MHz. This performance is superior to other RF front end SI cancellation schemes and demonstrates the potential applications of such device in a full-duplex wireless communication system.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"82 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79954430","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 characterization of G-RCT at very wide gate bias range with Vgs from -20 to 20V is predicted for the first time by using equivalent circuit model, which proves the validation of the proposed model.

For the investigation of an optimized design flow this study focuses on the three main steps of a millimeter wave switch design: identifying the optimum transistor gate width, large signal modeling of shunt transistors and the MMIC design. Based on the investigations of the optimum transistor gate width, it will be shown that insertion loss and output signal dynamic of a switch are directly correlated to the on-resistance of the utilized semiconductor technology. To prove the feasibility of this study, two RF SPDT switch MMICs, operating in the frequency range from 53 to 150 GHz and from 200 to 330 GHz, respectively, were designed and fabricated. Both switches show low insertion loss, high output signal dynamic, high yield and good agreement to the S-parameter simulations, based on the proposed shunt FET model. The proposed W-band and H-band SPDT switch MMICs achieve an insertion loss of 2 dB and 1.7 dB, respectively, and an output signal dynamic of up to 47 and 20 dB, respectively.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"4 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75346051","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}
