The system targets modulated spur interference, including main and image components and second order inter-modulation distortion. This architecture senses interference via an auxiliary analog path, and generates a reference signal for a widely linear based digital cancellation. A demonstrator, realized in 28 nm LP CMOS, is shown which is able to cancel blocker induced modulated spurs and second order inter-modulation distortion to the noise floor.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131968787","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 most cases sampling pulses are obtained through use of a step recovery diode (SRD). However, due to principle of their operation such diodes exhibit significant AM/PM conversion. We found out that this effect can be one of the important limiting factors to achievable phase noise performance. In this paper we propose method of applying additional DC bias to the SRD which should provide some limited control over AM/PM conversion effects. We present experimental results obtained by locking 1.3 GHz dielectric-resonator oscillator (DRO) to a 100 MHz reference.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123483627","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}

These residual errors are caused by an asymmetry of a thru/line standard and a load mismatch. To remove errors of the first type, we introduce a novel simple technique of the thru/line symmetrization, which utilizes an additional measurement of the same standard, but reversely connected to the VNA ports. To extract the load mismatch errors, we apply the multiline TRL (Thru-Reflect-Line) calibration as a reference one. To this end we use three common barrels of different lengths acting after their symmetrization as transmission line standards. With the VNA calibrated using the multiline TRL method, we characterize our mismatched load and then utilize its data to our modified TRM calibration. We show that this simple and low-cost approach results in improved accuracy of the TRM calibration. This aproach may be easily applied to enhance accuracy of the industrial VNA measurements on SMA devices.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124969010","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}
