| Abstract: | The design and realization technique of a rectangular wavegnide microcalorimeter based on a thermistor mount is presented. The effective effciency calculation method of the transfer standard is presented too. The thermopile output curves and transfer standard＇ s values is provided. The microcalorimeter will be national primary standard of millimeter-wave power. It enhanced China＇ s RF power measurement capability up to 75 GHz. International comparison is the base of the Mu- tual Recognition Arrangement （MRA） ,it is also the base of the international market tentry of China＇ s products, and the Key Comparison is the core of the international comparison. The key comparison of China＇ s WR-22 power primary standard is in- troduced in this paper. |
