This paper describes the development of a power standard based on thermocouple sensors. This work has been done in the framework of the fabrication of a microcalorimeter to destination of a foreign National Metrology Institute. The calibration has been performed in order to determine both the effective efficiency and the uncertainty for 21 frequency points up to 50 GHz. LNE expands its capability for manufacturing broadband (DC-50 GHz) primary calibration systems for RF power.
