This amplifier was designed for multicarrier reception (4 channels) of a 8PSK 140 Mbit digital radio link to be placed just behind the antenna, an arrangement which improves the performance of the repeater and allows for more sophisticated modulation or for the use of an all solid-state transmitter. However a delicate compromise between noise figure, gain and intermodulation products must be achieved: this is why a \"working area\" for the amplifier has been defined from experimental degradation (Multipath fading, constructive interferences, ...). Each stage of the amplifier has been optimized for this goal and 5 dB noise figure and 23 dBm intercept point have been obtained for a 17 dB gain amplifier.","PeriodicalId":429268,"journal":{"name":"1978 8th European Microwave Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126604239","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}

Two 300 channel carriers can be transmitted and it is therefore necessary that each amplifier should present the following characteristics : a 300 MHz minimum bandwidth, a 4 dB maximum noise figure, a 1 dB gain compression point of at least + 26 dBm, a 0.5°/dB maximum AM/PM conversion, a nominal output power of 15.5 dBm per carrier (for a 6 foot antenna), and a 46 dB overall gain. In order that the total system noise power be less than 200 pW, we show that for a 50 km link, a ± 15 km displacement around the centre of the link can be tolerated. An amplifier was built which meets these specifications. The 2 input stages were optimised for minimum noise measure, and the output stages were optimised for minimum intermodulation. Such a repeater, whose d.c. consumption is low (12 W) could easily be powered by solar cells and could be used on many inaccessable sites.","PeriodicalId":429268,"journal":{"name":"1978 8th European Microwave Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131336811","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}

Making use of coupled-transmission-line techniques and the Bloch-wave formalism for periodic structures, a method for coupled combline analysis is developed in the present paper. The method is exact under the homogeneous-dielectric assumption and yields excellent approximation for the microstrip case. The analysis is carried out by explicit formulae, ensuring high efficiency when numerically implemented. Thus the design problem can be solved by straightforward optimization.","PeriodicalId":429268,"journal":{"name":"1978 8th European Microwave Conference","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115101549","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}
