Uncertainty Components for RF Power Measurement between 110 GHz and 170 GHz

Commercial power sensors operating above 110 GHz frequencies have begun to be supplied due to the development of communication systems. However, the characterization of these power sensors is still a problem to be solved. In this study, the measurements performed for the identification of RF power sensors operating between 110 GHz and 170 GHz according to the thermal principle and the studies of determining the parameters of the power measurement uncertainty calculations based on these measurements are included. It has been shown that the uncertainty calculations of power measurements preformed with power sensors operating according to the thermal principle used in high frequencies and long-term measurements should take into account the thermal stability and linearity of the power sensor.
