The module achieves an overall conversion gain of 67 dB with a 3.2 dB noise figure. The MMIC chip set developed includes an LNA, an active splitter, phase shifters, a mixer, broadband power combiners and an IF amplifier. The assembly represents a significant size and weight reduction compared to conventional hybrid units.","PeriodicalId":231710,"journal":{"name":"Microwave and Millimeter-Wave Monolithic Circuits","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132986415","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}
