GaAs diodes from various manufacturers are tested. For comparison purposes, results for two different diode samples are presented. Correlation between different measurement techniques is observed which indicate the presence of traps in measured Schottky diode samples. I-V and C-V measurements show some trapping behavior. However, it is also important to observe frequency dependency of the diode capacitance and low-frequency noise properties to closely monitor the charge trapping in small area Schottky diodes. Diode samples are measured in on-wafer environment using a probe station.","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114054941","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}

Specifically, this new topology of waveguide technology provides advantages of low loss, high quality factor and easy RF packaging. In this paper we present the design methodology of millimeter-wave transition from standard WR-15 rectangular waveguide to inverted microstrip gap waveguide. Furthermore, a more practical power divider from standard WR-15 rectangular waveguide to inverted microstrip gap waveguide is also introduced. Both structures are vertical and there is no additional need for any complex modification of the waveguide structure to achieve compatibility between the two structures. The proposed two transitions cover the whole unlicensed 60 GHz band from 57 to 66 GHz in order to be widely utilized as an interface between gap waveguide feed networks and equipment components with WR-15 ports. The simulated results show promising S-parameters.","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128490220","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}

Signal-to-noise ratio (SNR) values above 35 dB within 6 dB input power dynamic are achieved with high voltage responsivity of 3000 V/W and significant white and 1/f noise reduction. The fabricated detector is characterized and compared to simulation results, proving a high accuracy level of the design and fabrication process, as well as excellent knowledge of the applied Schottky diodes. In a preliminary reliability assessment, the ACST low-barrier Schottky technology has proven very good stability without any diode failure during step stress tests, life tests, and environmental tests. The results demonstrate the suitability of the detector to be implemented in the 89 GHz receiver for the second European meteorological operational satellite programme (MetOp-SG).","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"39 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920237","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 resonance method is proposed for determination of the equivalent conductivity, which is based on measurements of unloaded Q factors of modes in resonators with minimized surface-to-volume ratio with only one flat wall formed by the metal surface under test.

We measure a high thermal response of 49000 K/W thanks to the small size of the Pt resistor and the thermal properties of the polymer. Furthermore, its small thermal capacity allows to decrease the time constant to 2.2 ms. A good matching in the entire W-band is achieved by a careful design of the probe. The linearity of the bolometer is demonstrated over 4 decades of RF power. As it is based on traditional microelectronic fabrication techniques, all dimensions of the circuit can be easily reduced to design full-band bolometers for smaller waveguides and higher frequency band up to the THz.","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130173123","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}

One of the key components of the future receiver is the polarizer, also known as orthomode transducer (OMT).
