To derive the circuit by experiments, we considered the lumped elements as a two-port network which was inserted into a microstrip transmission line for measurements. The network was first modeled as a general PI circuit first, and then finalized by the measured S-parameters. The method was applied to a surface-mounted device (SMD) resistor, a varactor diode, and a phototransistor working at the frequencies of 0.5-5 GHz. The derived circuit models were verified by their simulated S-parameters, which were in a very good agreement with the experiments. Our method provides a simple and effective way to build circuit models for lumped elements, which is helpful for their applications at microwave frequency. Specifically, our circuit model shows how the phototransistor changes its response under different illumination, which provides a way to use it in light-tunable devices.","PeriodicalId":301959,"journal":{"name":"2020 IEEE MTT-S International Wireless Symposium (IWS)","volume":"55 62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124771441","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}

In order to separate the current reduction from temperature effect clearly, the new self-heating extracted process has four steps. The first one is to extract the reference current parameters based on short pulsed I-Vat 25°C. Then, the parameters $(K_{I P K}, K_{P 1})$) related to current reduction are obtained using short pulsed I-V reduction at 85°C and 125°C. Thirdly, the parameters of self-heating thermal subcircuit with three time constants are determined by the long duration Pulsed I-V. Finally, this model is validated by the DC I-V. Using this process, the current reduction and temperature effect can be differentiated more clearly, and thus only two parameters ($(K_{I P K}, K_{P 1})$) are related to current reduction. The Angelov modeling is simplified, and the result agrees well.","PeriodicalId":301959,"journal":{"name":"2020 IEEE MTT-S International Wireless Symposium (IWS)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125042715","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}

As for the lumped part, a quasi-lumped resonator is designed by combining the interdigital capacitor and microstrip section inductor on both sides. Therefore, the employed resonator is inherently compact. As for the distributed part, the mutual coupling is introduced between the quasi-lumped resonators, indicating the proposed bandpass filter is not a simply lumped filter. In particular, the mutual coupling is a mixed electric and magnetic coupling, and two close-to-passband transmission zeroes (TZs) are accordingly generated with the proposed on-chip filter. For demonstration, a 28-GHz second-order BPF is designed and fabricated. The measured results indicate good features of low insertion loss of only 0.98 dB, high selectivity, and wide stopband suppression.","PeriodicalId":301959,"journal":{"name":"2020 IEEE MTT-S International Wireless Symposium (IWS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125784500","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}

Firstly, a broadband transition between the SACPS and the defected ground microstrip line which has the same characteristic impedance of the SACPS is designed. Then, a broadband transition between the defected ground microstrip and the microstrip line which has the characteristic impedance of 50 Ω is designed by using a tapered impedance matching section.
