The method also provides good accuracy, wide dynamic range, easy de-embedding features and other advantages. Being heavily dependent on Digital Signal Processing (DSP), it is perfectly suited to the modern trend of computation-intensive RF instrumentation.","PeriodicalId":264877,"journal":{"name":"37th ARFTG Conference Digest","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130812330","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}

At 27 GHz, the system is capable of reflection coefficient magnitude accuracy better than 0.007, phase error less than 4 degrees, and gain uncertainty less than 0.15 dB. Reflection coefficient measurements are corrected by flrst using a standard network analyzer TRL calibration routine and then converting it to two one port calibrations. Correction of the power measurements is not as straight forward. Sources of error in the power measurements and methods to reduce this error are discussed.","PeriodicalId":264877,"journal":{"name":"37th ARFTG Conference Digest","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123315312","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}
