This heterodyne system offers more than 50 dB of dynamic range. Calibration of optical phase and amplitude modulators is achieved by downconverting a sideband of the modulated optical carrier to a fixed intermediate frequency with another laser. This technique eliminates the need for a high-speed receiver. This dual YAG system is capable of generating beat frequencies from DC to more than 100 GHz.<<ETX>>","PeriodicalId":339513,"journal":{"name":"1988., IEEE MTT-S International Microwave Symposium Digest","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131189916","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 purpose is to identify what statistical FET data is needed to statistically design a high-yield monolithic microwave integrated circuit (MMIC) amplifier. An example is used to identify which aspects of statistical circuit design are sensitive to the proper FET model statistics. It is shown that the design values are insensitive and the yield estimates are sensitive. The important issues in statistical circuit design are summarized and a discussion of the needed future works is given.<<ETX>>","PeriodicalId":339513,"journal":{"name":"1988., IEEE MTT-S International Microwave Symposium Digest","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132508104","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}

An additional two measurements are obtained by switching a phase delay into one of the paths. These four measurements are manipulated using six-port theory to calculate the complex reflection coefficient. A 27-40-GHz prototype operating as a reflectometer is demonstrated.
