These have been obtained through the DXO's ability to generate high ratio of output power to crystal power dissipation, and to do this at transistor operating current levels selected for the lowest noise figure independent of crystal current. These, combined with a novel automatic level control circuit (ALC) that does not reduce transistor current, has made these results possible.","PeriodicalId":291824,"journal":{"name":"39th Annual Symposium on Frequency Control","volume":"402 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133200200","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}
