This paper reviews the methods for accurate on-wafer measurements of noise temperature and details the preliminary design and construction of the transfer standards. Measurements are presented of their noise temperatures at frequencies from 8 to 12 GHz. Such transfer standards could be used in interlaboratory comparisons or as a verification tool for checking on-wafer noise calibration accuracy.","PeriodicalId":208002,"journal":{"name":"51st ARFTG Conference Digest","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114650632","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 vector based system is able to account for the various impedance mismatches at the calibration test port, thus mathematically eliminating the mismatch uncertainty component of the power calibration. With scalar based systems, this component is a major contributor to the overall calibration uncertainty. With the new vector based system, the overall calibration uncertainty is significantly reduced. This paper will discuss the new system in detail, and show measurement data and associated uncertainties.","PeriodicalId":208002,"journal":{"name":"51st ARFTG Conference Digest","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114754945","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}

Experimentation was conducted to study the sensitivity of the measured results to various parameters within the system, including oscillator-under-test power level, and the need for an isolator in the test system. The results show that the phase noise measurement is relatively robust to power level variations within the system, and that the isolator, although bandwidth limiting, does perform a necessary role for the measurement. A pair of 1.4GHz free running oscillators are used as test cases in this study. Measurements from the injection locking technique are compared to those made using the more traditional detector and discriminator methods.","PeriodicalId":208002,"journal":{"name":"51st ARFTG Conference Digest","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122037324","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}

This paper describes the development and deployment of instrumentation to determine the frequency response of 2.4 GHz indoor wireless channels. The instrumentation is developed around a HP 87146 vector network analyzer and includes the required amplification for measurement of responses at a transmit-receive separation of up to 33 meters. While designed primarily to gather data for development of accurate small-scale multipath models, the setup is calibrated to also provide the absolute signal levels necessary for shadowing and path loss characterization. The system design and link power budget are presented along with the criteria for selecting the individual components. In addition, the methodology for correction of magnitude and phase responses of the components is detailed. Finally, the measurement campaign is described, and sample results are presented that exhibit the frequency- and time-selectivity of these channels.","PeriodicalId":208002,"journal":{"name":"51st ARFTG Conference Digest","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124071611","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}
