This heterodyne transceiver improves the system sensitivity over the previously reported homodyne approach. The complete transceiver has better than 12-dB suppression of the image sideband with a nominal LO drive of 9 dBm and is estimated to exhibit a 11-dB noise figure for IF as low as 1 MHz. This MMIC chip was fabricated using TRW production line process and is suitable for automotive radar applications.","PeriodicalId":328819,"journal":{"name":"Proceedings of 1994 IEEE GaAs IC Symposium","volume":"57 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126389718","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}

Further scaling will involve performance fall-offs as critical dimensions are relaxed in order to reduce leakage currents. Compound semiconductor HFETs will suffer similar scaling penalties. Thin film SOI can extend silicon scaling by two or three generations. However, by the year 2000, a new technology will be necessary to continue the performance trend. That technology will likely utilize quantum effects to increase the functionality of individual electronic devices. The barriers to scaling MOSFETs and HFETs as well as examples of worldwide progress in developing quantum-based technology for future ULSI applications operating at room temperature are discussed.","PeriodicalId":328819,"journal":{"name":"Proceedings of 1994 IEEE GaAs IC Symposium","volume":"2154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130031672","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}
