Abstract The WR-42 power standard is a micro-calorimeter system that uses DC substitution and calorimetry techniques to measure the effective efficiency of the WR-42 thermistor mount. The uncertainty assessment of effective efficiency in WR-42 micro-calorimeter system is introduced, and the measurement results of effective efficiency and uncertainty are given. The development of this power standard fills the gap between 18GHz and 26.5GHz, which help Chinese RF power standard fully cover the frequency band between 10 MHz and 220GHz.
