The complex permittivities of binary liquid mixtures of methanol and ethanol are reconstructed from the resonant frequency and the quality factor.

The results show that there is more relation between OIP3 and the collector current than between OIP3 and the collector emitter-voltage. The proposed formula is applicable for collector currents in the range of 2 mA to 8 mA and for collector-emitter voltages in the range of 2 V to 3 V.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126234091","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}
