Zusammenfassung
Accurate measurement of radio frequency and millimeter-wave power is essential for establishing traceability in high frequency metrology, particularly in wireless communication and radar systems. Waveguide microcalorimeters serve as primary standards by enabling precise radio frequency power measurements. A critical parameter in these systems is the correction factor, which compensates for radio frequency losses of the microcalorimeter and significantly influences measurement uncertainty. This paper presents a comparative study of correction factor determination in waveguide microcalorimeters across multiple frequency bands, ranging from 8.2 to 220 GHz. Three established techniques, namely the offset short method, the foil short method, and the vector network analyzer method were investigated using a R-500 waveguide microcalorimeter. Experimental evaluations demonstrate good agreement among the correction factors obtained from all three methods. An optimized implementation of the foil short method is proposed to enhance measurement effciency. The comparative results highlight the strengths and limitations of each approach, offering National Metrology Institutes a practical basis for selecting appropriate techniques for the characterization of microcalorimeters.
