The significance of this investigation is that at sub-millimetre-wave or THz frequencies, where the waveguide features are less than 100μm and the skin depths are less than 200nm, the exact conductor shape and surface roughness have a significant electrical effect and any variations result in an important disagreement between the modelled and measured characteristics. This is a proof of concept validation of the rapid manufacturing approach and is aimed at paving the way to a range of THz passive waveguide components, where the availability and cost of such components is typically prohibitive and where the surface roughness is minimized and highly reproducible. Using this approach the fabrication times can be as rapid as a few days and can yield many hundreds of highly reproducible millimetre scale components.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127180963","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}

For different frequencies, the proposed transmitter can simultaneously employ 1-bit Low-pass and Band-pass delta-sigma modulators structures, or employ hybrid structures. Carrier frequencies are equal to oversampling frequencies of modulators. Besides, signals on two carriers are not interfered with each other to ensure transmission dual-band signal. Performance analysis is simulated by using Matlab/Simulink. The simulation results achieve high signal-to-noise radio and show the effectiveness of the proposed architecture.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125101568","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 method, a high linearity LFM waveform is generated by a direct digital synthesis (DDS) module. The phase and magnitude errors of the output LFM signal are sampled and analyzed by a digital oscilloscope. The pre-distortion coefficients can be calculated according to the measured data. The process of compensation is implemented by modulating the LFM waveform with pre-distortion coefficients from baseband signals. To verify this method, a wideband LFM waveform generator with predistortion compensation is designed and tested. The measured results show that, with compensation, the magnitude and phase errors can be evidently improved (the peak magnitude deviation is from 4.8 dB to 0.2dB, the peak phase deviation is from 60° to 15°, and the linearity performance of LFM waveform is improved to be less than 7×10-5) within a 1.5GHz-wide frequency bandwidth.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122741995","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}
