All measurements are achieved in the time domain; the errors are corrected in the frequency domain, after Fourier transform. The bandwidth of the system extends from DC to 20 GHz.

Thus, compared to conventional MMIC mixers, a significant improvement in extracting the IF signal to achieve a broad bandwidth performance is possible. On-chip matching circuitry is included between diodes and baluns to enhance performance across a 6-GHz IF bandwidth.<<ETX>>","PeriodicalId":165665,"journal":{"name":"1992 IEEE Microwave Symposium Digest MTT-S","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130716112","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}
