Examples are described, and proposals to exploit this process at millimetre wavelengths for the provision of phase locked frequency division are presented. Various systems are considered, and it is suggested that a diode having charge storage time of 10 picoseconds an injection voltage of about a volt, and a charge storage capacity of about l0^5 electrons would provide an ideal device to divide a 50GHz signal at a power level of around l0mW. For modulated signals with l00MHz carriers, phase locked division is demonstrated in which the amplitude and frequency excursions of a carrier are faithfully followed at speeds representing a fractional bandwidth of at least 10%.","PeriodicalId":227595,"journal":{"name":"1986 16th European Microwave Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122584285","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}

This paper describes a low conversion loss upconverter which has been designed to operate over a wide bandwidth with a high level of intermodulation suppression in a space environment. The design and measured performance of an E-plane upconverter for frequency conversion from 4 to 20 GHz is described. The mixer uses beam-lead diodes and is realized in a single-balanced configuration on a soft substrate. The circuit is clamped in the E-plane of a waveguide housing. The conversion loss of the mixer is 6.5 ± 1.1 dB over a 700 MHz RF bandwidth for LO power levels of +11 dBm to +15 dBm, and more than 40 dB suppression of 3rd order intermodulation products is achieved. Thermal and vibration test data show that this configuration is rugged and thus has potential for application in space and other hostile environments.","PeriodicalId":227595,"journal":{"name":"1986 16th European Microwave Conference","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125487520","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}

Theoretical analyses of Finline have mainly been concerned with the fundamental mode with little published on higher order modes or the assessment of losses. Although recent work on higher order modes has gone so far as to predict complex mode propagation under certain circumstances, it has been widely acknowledged that searching for higher order modes becomes increasingly difficult with higher mode order. Since knowledge of these modes is essential for the analysis of discontinuities further work is needed in this area.","PeriodicalId":227595,"journal":{"name":"1986 16th European Microwave Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127020811","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 efficiency depends on the varactor parameters and the embedding impedances seen by the diode at fundamental and harmonic frequencies. Mm-wave doublers were simulated with a computer to find optimum embedding impedances for a given diode. A scaled model was constructed in order to search for optimum impedances for wide-band doublers in practice. For experimental verification a doubler from 40-60 GHz to 80-120 GHz was constructed. An efficiency > 30 % was obtained at the output frequency range from 75 to 96 GHz at various input power levels between 2 and 20 mW. The highest efficiency measured was 42 % at 88.6 GHz with 10 mW input power.","PeriodicalId":227595,"journal":{"name":"1986 16th European Microwave Conference","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127554717","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}
