Screen printing technology has provided coplanar waveguides (CPW) lines with low transmission loss and high precision contact repeatability at millimeter-wave frequency up to 110 GHz. The paper demonstrate capability of the screen printed CPW as an ISS for on-wafer measurements. Standard lines with seven different lengths were designed and fabricated by screen printing technology. In the paper, Multiline ThruReflect-Line (TRL) calibration was performed by using ISSs fabricated by both screen printing and conventional pleated technologies. Regarding calibration capability validation, contact repeatability performance was first tested, then, verification devices were measured. According to comparison results, results obtained by calibration of screen printing ISS are almost the same as results measured based on conventional ISS tech.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132674741","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 reel-to-reel printing process uses inkjet printing as a precursor for 2μm copper plating, which allows significantly lowered resistances as compared to traditional inks. A multiline TRL calibration technique has been used to characterize the propagation constant and reflection coefficient of the CPW lines. With the aid of four sets of measurements at two identical labs, it is shown that the fabricated samples have contact repeatability, permitting redundant multiline calibrations.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127150359","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}

Even if above 110 GHz frequency, metrological traceability is universally important, however the system set-up and calibration method are as important as the metrology standards due to high cost and low stability / reproducibility for the measurement system and standards as compared to those in the microwave frequency range. In recent years, operation frequency of commercial vector network analyzers (VNA) reaches currently up to 1.6 THz. Key priorities for improvement of VNA measurement accuracy are waveguide interface performance, operation conditions, hardware set-up, calibration standards and methods. Then, measurement traceability and uncertainty, further verification process, including measurement comparison, are absolutely necessary for quality of measurements. The presentation introduces all key priority together with latest research achievements, then gives recommendation for accurate VNA measurement in Terahertz.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121875164","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}

Classically, there have been several solutions to these problems but these have often been slow or have required sometimes complicated reference-generation schemes to enable phase recovery. By employing a wide-IF digitizer in a sampling receiver along with a somewhat novel triggering/marking scheme, it is possible to perform synchronous complex measurements during a frequency or power sweep at 10s of μs/point sweep rates. This configuration is demonstrated with a waveform reconstruction experiment and with sensitive swept transient DUT measurements delineating thermal response differences of more than 1.5 dB and 15 degrees on a fast sweep timescale.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130175159","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 a novel orthogonal identification (direct extraction) of current source and charge source contributions to the spectrally rich port currents under large-signal conditions. Explicit decomposition formulae, applied entirely in the frequency domain, are derived in terms of sensitivity functions at pairs of large-signal operating points related to one-another by time-reversal transformation. The method is applied and validated with respect to data from a measurement-based model of a pHEMT transistor. It is demonstrated that the scalable model can predict the nonlinear performance of the transistor over several orders of magnitude in frequency, all from X-parameters at a single fundamental frequency.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124270761","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}

Harmonics can fall into bands that are used for other services so prior evaluation of those harmonics is critical in product development. An on-wafer harmonic bench is used for fast evaluation of material and designs without having to build a final product to predict what the harmonic performance will be. Harmonic measurements are not new; but high power (4 watts), on-wafer harmonic measurements present hurdles that have not been solved. Low passive intermodulation (PIM) components, probe selection, connector selection and bench configuration all play into building a measurement system with low enough system noise to be able to evaluate the state-of-the-art technologies for mobile applications.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124130862","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 paper presents an active loadpull (ALP) testbed which performs continuous wave measurements with the LSNA for arbitrary loads and substrate temperatures while jointly measuring the device die temperatures with an infrared sensor. Measurements are performed for a 15 W GaN HEMTs for 15, 25, 35 and 45 C substrate temperatures. The thermal resistance is extracted from the dissipated power and temperature data for fundamental loads spanning the entire Smith Chart. The quasi linear relation between the dissipated power and the device temperature increase measured for all loads verifies that a physical temperature is measured. The expected correlation between the dissipated power, output power and device temperature is also evidenced. This ALP testbed provides thus a wealth of joint loadpull, thermal and loadline data which should facilitate the extraction of an electrothermal device model directly from large-signal RF measurements.","PeriodicalId":170825,"journal":{"name":"2015 86th ARFTG Microwave Measurement Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130718293","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}
