NPL, PTB, and LNE designed and produced three different microcalorimeters for the WG29/WR7 band. The microcalorimeters used different correction methods to characterize effective efficiency. Finally, the three laboratories measured thermoelectric power sensors from 110 GHz to 170 GHz to demonstrate equivalence and results show good agreement.
