Microwave power amplifiers provide good heat dissipation and require a degree of redundancy. Each of the amplifiers included in the redundant microwave power amplifier is made on boards located perpendicular to the heat-stabilized plate and fixed on the plate on one or both sides. The area occupied by a duplicated or triple redundant microwave power amplifier does not exceed the area on a thermally stabilized plate required to remove heat from one microwave power amplifier included in its composition. And for a triple redundant microwave power amplifier – the area required for heat removal from two such amplifiers.","PeriodicalId":117144,"journal":{"name":"Infocommunications and Radio Technologies","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132271195","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}

As the lengths of long-distance telephone lines increased, two problems arose that were rec-ognized as particularly relevant, in particular, crosstalk and signal attenuation. AT&T researchers were engaged in solving these problems. This article examines the work of scientists and engineers who have led to real practical solutions to problems of long-distance telephone communication, in particular, Oliver Heaviside, John Stone and George Campbell.","PeriodicalId":117144,"journal":{"name":"Infocommunications and Radio Technologies","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126859829","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 problem of creation of UWB direct chaotic transceivers using VHF and UHF frequency bands is investigated from both the theoretical point of view and its practical implementation. Potential characteristics of the devices working in these bands are estimated, such as transmission rate, communication distance, energy consumption, error probability rate and link margin calculus. In the experimental part of this work, the development of transceiver mockups operating in 200–450 MHz band is described, as well as their structure, technical implementation and characteristics. The results of laboratory and field experiments with the created mockups show that they are capable of data transmission exceeding one kilometer.","PeriodicalId":117144,"journal":{"name":"Infocommunications and Radio Technologies","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131640822","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}
