Comparaison bilatérale de mesure de puissance hyperfréquence entre 50 MHz et 18 GHz

摘要

This paper deals with the results ora bilateral comparison measurement of the effective efficiency q of two 50Ω/N type and two 50Ω/7 mm coaxial thermistor RF power standards, at eight frequency points between 50 MHz and 18 GHz. Two laboratories participated to this compartson, the NMi-VSL (Netherlands) and the BNM-LCIE (France), which acted as pilot laboratory. Both used a symmetrical twin type microcalorimeter for the efficiency determination. The results show a satisfying level of agreement between the two laboratories All the results for are within an interval of O. 002, except for one thermistor mount, which maximum deviation between the two laboratories is 0.005 at 8 GHz.
