Abstract

A broadband rectangular waveguide calorimeter for power sensor calibration in the millimeter-wave region is presented in this study. The calorimeter has a dual-load structure, an operational frequency range of 26.5 GHz to 40 GHz, and high substitution efficiency and sensitivity. Its effective efficiency uncertainty is 0.74%~1.1%.
