In this paper, a robust validation approach is identified and used to compare a number of completely different large-signal measurement systems. Unlike a previous ‘round-robin’ exercise, the solution does not require an accurately modeled non-linear reference component to account for system impedance variations when comparing results, which clearly introduces additional complexity and the possibility of errors. Instead, active loadpull, coupled with a common passive source network is used to present a consistent impedance environment to a device under test. After employing this method, large signal data from two completely different measurement architectures employing different instruments and calibration procedures showed excellent agreement. This approach has proved useful in the validation and comparison of a number of large signal measurement and could be used to increase confidence in such systems.","PeriodicalId":273767,"journal":{"name":"2008 IEEE MTT-S International Microwave Symposium Digest","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129392350","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 inverters are either implemented through complementary split ring resonators (CSRRs) or through complementary spiral resonators (CSRs). By using the left handed and right handed frequency bands of the inverters, the required phase shifts, −90° and +90°, at the respective operating frequencies, ƒ<inf>1</inf> and ƒ<inf>2</inf>, can be obtained, whereas the characteristic impedance can be set to the necessary value to achieve effective input matching (Z<inf>o</inf>=35.35Ω for a 1:2 power splitter). The main advantages of these devices are: (i) dual-band operation with arbitrary ƒ<inf>2</inf>/ƒ<inf>1</inf> ratio, due to the possibility of engineering the dispersion diagram of the impedance inverter; (ii) compact size, owing to the small electrical size of CSRRs or CSRs; and (iii) full compatibility with planar technology, since neither lumped elements nor vias are used. The reported examples are two dual-band Y-junction power dividers operative at the mobile GSM bands (ƒ<inf>1</inf>=0.9GHz, ƒ<inf>2</inf>=1.8GHz). The area occupied by the CSR- and CSRR-based divider is 0.11λ×0.09λ and 0.14λ×0.12λ, respectively (where λ is the guided wavelength at ƒ<inf>1</inf>) and their measured characteristics are good.","PeriodicalId":273767,"journal":{"name":"2008 IEEE MTT-S International Microwave Symposium Digest","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130946889","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}
