We studied a variable noise source using a precision variable attenuator in the frequency range of 50 - 75 GHz, and its uncertainty was analyzed in detail. To determine the noise temperature of the noise source, the variable attenuator was calibrated

We have experimentally evaluated the equivalent noise temperature (ENT) of a microwave standard noise source. The resistivity and its temperature coefficient of a transmission line (TL) of the noise source were determined by the curve fitting techniq
