The active device considered is a GaAs Dual-Gate MESFET with submicrometer gate length. The frequency range of the output signal is from 1 up to 21 GHz, for an input frequency between .1 and 1 GHz. As a typical result, a higher multiplication factor value up to 200 has been obtained and a maximum output frequency of 40 GHz has been observed. Consequently, two main applications can be proposed: - first: as a broadband comb-generator - second: as a very simple crystal controlled high frequency generator.","PeriodicalId":177448,"journal":{"name":"1985 15th European Microwave Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134360226","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 radar includes features like pulse-to-pulse frequency agility within a 400 MHz bandwidth, wide PRF-range from 1-50 kHz with fixed and staggered PRF. The polarisation of the transmitter is switchable from pulse to pulse either from RHC to LHC or from horizontal to vertical depending on the primary feed of the 300 mm cassegrain antenna which is used. Two identical receivers are included for co- and cross-polarized signal reception. A linescanner using a flat mirror has also been built. A rotating speed of 600 rpm gives a scanrate of 20 scans/second using both sides of the mirror.","PeriodicalId":177448,"journal":{"name":"1985 15th European Microwave Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130910739","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 uncertainty of measurement is ± 0.02 for the absolute value and ±2° for the phase angle of the reflection coefficient.
