Abstract (en)

[origin: WO2023001608A1] The invention relates to a device and a method for electrically characterizing properties of materials, assemblies, and/or components in an environment with a high temperature, for example in order to characterize electromechanical SAW components with respect to the function thereof under action of temperature. The aim of the invention is to develop a device which allows a fail-proof positioning of a measuring object, a quick and simple change of the measuring object, and a reliable characterization at high temperatures. This is achieved by a device containing a sample holder which has means for a galvanic or capacitive in-coupling and/or out-coupling of electric signals, at least one support element, at least one high-temperature waveguide, at least one low-temperature waveguide, wherein at least the high-temperature waveguide(s) is/are designed as a coaxial conductor with solid dielectricum elements made of electrically non-conductive ceramic, at least one coupling component, at least one heat shield, at least one temperature sensor which is arranged in the support element, and at least one flange part.
