In this paper, we show that this placement changes the nature of the probe. Thus,, the \" error\" two-port, which separates the device under test from the ANA, depends on the particular standard being measured. This inserts an unremovable error into the calibration. An electromagnetic analyses of several coplanar waveguide standards is provided to support this hypothesis. A means of testing when the error is significant, compared to other measurement errors, and a solution to the problem are presented.","PeriodicalId":153615,"journal":{"name":"34th ARFTG Conference Digest","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126951275","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}

Each of these outputs is a valuable tool for analyzing and minimizing residual calibration errors. The corruption factor is a sensitive measure of the aggregate contributions of all departures from the ideal situation. For example, if one of the calibration standards is a short, we can determine how closely it approaches the ideal magnitude, |Γ|= 1, and phase, argΓ = 180/°. Our experimental evidence has shown that, at 40 GHz, |Γ| for a coplanar short directly contacted by the probe is about 0.7 dB smaller than that for a short seen through a length of coplanar line on the substrate. Thus, lower corruption and residual calibration errors are obtained if the reference plane is defined on the substrate at some distance away from the probe tips. We have corroborated the work of others(4) by modeling the short as a small reactance and shown how further improvements are achieved by separating the substrate from the wafer chuck by a low-dielectric spacer.","PeriodicalId":153615,"journal":{"name":"34th ARFTG Conference Digest","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133817037","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 key difficulty in the system calibration is obtaining the excess noise ratio (ENR) provided by the noise source at the MMIC wafer probe interface. This problem is overcome by performing error corrected vector S-parameter measurements of the input transition network, which consists of a waveguide terminal on one end and a probe tip on the other. These S-parameters are then used to obtain noise calibration reference planes at the probe tips. To demonstrate the system, noise figure and gain measurements for three MMIC amplifiers are presented.","PeriodicalId":153615,"journal":{"name":"34th ARFTG Conference Digest","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133112517","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}
