The principle of its operation requires a complex circuitry which has to convert tihe reference and test signals to an intermediate frequency while keeping the same phase and amplitude relation between them. This makes the equipment very complex and expensive especially at millimeter wavelengths. A cheaper and practical alternative for the network analyzer was introduced by Glenn Engen and Cletus Hoer in the 70's at the National Bureau of Standard, Colorado.","PeriodicalId":219944,"journal":{"name":"SBMO International Microwave Conference/Brazil,","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116645833","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 motivation foir this effort was the recognition that the most commonly used prediction method, the one currently recommended by the CCIR, was developed with basis on a limited amount of data measured in temperate climates and offers poor results when applied to sites in tropical and equatorial regions. It was found that some improvement can also be obtained for temperate climates, taking advantage of the larger set of experimental results now available in the CCIR data bank.","PeriodicalId":219944,"journal":{"name":"SBMO International Microwave Conference/Brazil,","volume":"24 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133570529","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}
