In this investigation, an alternative approach to measure the perturbed resonator by incorporating it within an oscillator loop is described. It has the advantages of simplicity in design and offering direct readout of the oscillator output frequency, which enables the electric field at the location of the dielectric bead to be readily determined. The theoretical basis and the experimental arrangement are described in detail. Measurement data obtained by this method for the axial field distribution of a resonant cell taken from an L-band coupled-cavity accelerating structure are presented.","PeriodicalId":345451,"journal":{"name":"2006 67th ARFTG Conference","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134402293","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 method is based on the principle of ¿null double injection¿, a technique that consists of simultaneously driving the input and test ports of the reflectometer with sources whose relative amplitudes and phases are adjusted to produce nulls at the detector outputs. This six-port-to-four-port reduction technique permits the network constants to be determined simply from ratios of measured power at the remaining (unnulled) ports. Application of the technique to a prototype non-contacting reflectometer is demonstrated. The measurements of reflection coefficient for a set of loads taken by the prototype non-contacting reflectometer using this calibration method show good agreement with the ones by HP 8720C vector network analyzer, with measurement discrepancy less than 2% for 6 dB and 10 dB attenuators and less than 4% for the offset short over the frequency range from 1 GHz to 1.5 GHz.","PeriodicalId":345451,"journal":{"name":"2006 67th ARFTG Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126177559","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 multiport calculation (MC) procedure supports all two-port calibration methods e.g. SOLT or LMR without any additional standard. Small included approximations have no influence on the quality of practical measurement results. This developed MC-procedure works with vector network analyzers with three or four measurement channels to measure two-port paths of n-port devices with high accuracy. A switch matrix can be used to simplify the measurements. The presented calculation algorithm of the MC-procedure is out-standing regarding the simplicity and numerical robustness. The algorithm allows an easy programming for the correction of measurements of any device independent of the number of ports (3 to n). Experimental results attest the very good precision of MC error corrected measurements.","PeriodicalId":345451,"journal":{"name":"2006 67th ARFTG Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124616335","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}

Power amplifiers are difficult to design since the available design techniques are not valid for the more complex modulation schemes used nowadays. Therefore, one needs to include information about these complex signals in the design strategy. But this information should be used such that it allows the designer to take good design steps. We reviewed the traditionally used load-pull design technique for power amplifier designs using multi-tone excitation signals to MIMIC the real excitation signals. This approach is illustrated on the loadpull characteristics of a 5 GHz power amplifier in 0.13 ¿m CMOS technology. This example shows the difference in design choices when using the correct excitation signals. Therefore, it illustrates the importance of these methods and the excitation signal used.","PeriodicalId":345451,"journal":{"name":"2006 67th ARFTG Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130824887","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}
