Microcalorimetric techniques with thermoelectric transfer standards

The paper describes the realization process of the high frequency power standard with a twin broadband microcalorimeter designed for effective efficiency measurement of power sensors based on thermocouples. The process includes the important step of the microcalorimeter self- calibration and auxiliary S-parameter measurements necessary for evaluating the system error correction. Besides the previously used microcalorimeter measurement techniques, this paper proposes a measurement method able to lead to the final result overpassing the corrections step or the use of the extrapolated values
