“…This definition reduces to the typical one given in [19] for bolometers, if we identify P M with the power measured by dc-power substitution. On the other side, we demonstrated in [15] that (1) matches perfectly the alternative definition assumed in [11].…”

“…In the past, the international community conducted a comparison, based on PTB suggestions [10], by circulating power sensors based on indirectly heated thermocouples among NMIs, with the aim of testing the suitability of thermoelectric detection for the coaxial microcalorimeter, as an alternative to the resistive power sensors, i.e., bolometers, no longer readily available on the market at frequencies greater than 18 GHz [11]. The Istituto Nazionale di Ricerca Metrologica (INRIM), formerly IEN Galileo Ferraris, participated in the international comparison mentioned in [11], i.e., CIPM key comparison CCEM.RF-K10.CL-power in coaxial PC 3.5 mm line system, with a coaxial microcalorimeter optimized for thermoelectric power sensors.…”

This paper describes a comparison of microwave power standards based on thermoelectric sensors to an analogous standard based on bolometric sensors. Measurements have been carried out with the classical twin-type microcalorimeter, fitted with N-connector test ports suitable for the frequency band 0.05-18 GHz. An appropriate measurand definition is given as being suitable for both standard types. A system accuracy assessment is performed applying the Gaussian error propagation through the mathematical models that interpret the microcalorimeter response in each case. The results highlight advantages and weaknesses of each power standard type.

This paper describes a thermoelectric waveguide power sensor for the frequency range 75-110 GHz, which has been calibrated in a waveguide twin-type microcalorimeter. The sensor is suitable as a transfer standard to provide traceablity for high-frequency power calibrations. The design and calibration of the sensor are described. The calibration is based upon a novel measuring quantity, referred to as generalized efficiency. The results of mirocalorimeter measurements and sensor performance are given. The new transfer sensor is tested against conventional thermistor waveguide sensors in a direct comparison setup, showing good agreement within the estimated uncertainties. Index Terms-Millimeter-wave power transfer standard, thermoelectric power sensor, traceability, twin-type microcalorimeter, waveguide power sensor. Rolf H.

“…Afin de pallier cette contrainte, l'utilisation d'un thermocouple remplaçant la thermistance apparaît comme une solution cohérente pour des caractérisations dans les basses fréquences. Des détecteurs de puissance basés sur les thermocouples à chauffage indirect ont fait l'objet d'une comparaison internationale (CCEM.RF-K10.CL) [2] dans laquelle a été expérimenté pour la première fois un microcalorimètre symétrique sur ligne coaxiale spécialement optimisé pour ce type de capteurs. Les résultats de cette comparaison ont permis de conclure que ces sondes étaient une réelle alternative aux thermistances afin de réaliser un étalon de puissance jusqu'à 26,5 GHz.…”

Cette publication présente la réalisation d'un nouvel étalon de puissance à partir d'une sonde à thermocouple commerciale. Un étalonnage au microcalorimètre a été effectué afin de déterminer l'efficacité effective de la sonde. Un étalonnage par la méthode de transposition thermique a contribué à valider les résultats obtenus au microcalorimètre. Le LNE s'est doté ainsi d'un nouvel étalon de puissance pour les basses fréquences.
