This millimeter wave source is used as local oscillators (LO) in a passive millimeter wave imaging system. It achieves a -90.46 dBc/Hz (at 10 kHz offset 92 GHz carrier frequency) phase noise performance, the spur level is lower than -60 dBc. A well matched low insertion loss waveguide four-way power divider is designed, and its output power is more than 12 mW at each output port. In addition, analysis indicates that the wideband LO noise performance is critical in passive millimeter wave imaging systems. Therefore, a transmission type cylinder cavity is arranged before the power divider, which can effectively reduce the wide band noise of the millimeter wave source.","PeriodicalId":304483,"journal":{"name":"2008 Global Symposium on Millimeter Waves","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125388445","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}

However, there is little information about their dielectric properties in the millimeter-wave regions. To obtain their dielectric properties, an automatic open resonator measurement system at Ka-band is designed and constructed. The method of multi-frequency points measurement with frequency variation technique is adopted in order to realize the precision determination of cavity length over a broad band. After the checking of repeatability, credibility, reliability and stability, the stability and high accuracy of the measurement system are ensured. It is called certified measurement system and is used to measure the above materials. The results of lots of measurement show that the standard deviation of measurement error is less than 0.154% in permittivity and 19.61% in loss tangent. Meanwhile, some experimental summaries on the open resonator technique are provided. Software that controls the measurement systems is developed and it improves greatly the measurement efficiency.","PeriodicalId":304483,"journal":{"name":"2008 Global Symposium on Millimeter Waves","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121916992","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}
