Due to the regulatory issues the transmit power is strictly limited, therefore larger ranges can be achieved by using the receivers with best noise handling properties. In this paper several UWB transceiver architectures, most commonly encountered in the literature, are selected and compared with each other. From this group, three receiver structures are chosen for a simulation-and measurement-based performance verification in terms of the Signal-to-Noise Ratio in the processed signal. The firm base for the comparison among the architectures is assured by the common hardware. The implemented generic UWB transceiver enables the realization of different receiver structures by introducing only minor modifications.","PeriodicalId":266910,"journal":{"name":"2012 42nd European Microwave Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132638276","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}

When the probe is operated under in-situ conditions, improvement of the probe sensitivity to variations in the permittivity of the liquid was observed. Measurements of the quality factor of the resonator reveal that the probe is able to resolve variations around 0.04 in e' for low loss liquids. The spatial resolution of the probe is 10 μm, and was experimentally verified by scanning a MMIC detector covered with a 30 μm thick layer of mineral oil, at a standoff distance of 10 μm. Scanning results confirm that the presence of the mineral oil layer on top of the circuit improves the sensitivity of the probe without degrading the spatial resolution.
