The nonlinear behaviour of the intrinsic elements are expressed using two-dimensional spline-functions. The large-signal simulation considers all nonlinear intrinsic elements including the Schottky-diodes and the gate-drain avalanche breakdown.","PeriodicalId":248044,"journal":{"name":"1990 20th European Microwave Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121899585","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}

In this paper, the use of a new approach, the \"Harmonic Describing Function\" (HDF), is proposed to study the nonlinear device behaviour without restrictions in the harmonic content of signals involved in the analysis. HDF, evaluated by means of harmonic balance technique, describes the nonlinear device together with the linear network in which it is integrated, so the harmonic content of signals appears as a result of the analysis.","PeriodicalId":248044,"journal":{"name":"1990 20th European Microwave Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129639485","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}

The CDW contribution to conductivity of such conductors results in unusual electric properties: frequency and electric field dependent conductivity, current oscillations, etc. These properties ensure possible practical applications of LDC's in microwave electronics: sensitive bolometers as well as expanded dynamic range mixers and electrically and optically controlled switches. The bulk nonlinear properties of these materials are used, which leads to simple designs, eliminating the need for submicron technique. LDC's exhibit nonconventional electric properties which enables their possible applications in microwave electronics to be discussed. They have an anisotropic crystal structure accompanied by a strong anisotropy of electric properties.
