Yv. Kistovich et Og. Petrosyan, CALCULATION OF THE TEMPERATURE DISTRIBUTION ALONG THE TRANSMISSION-LINE OF A THERMAL NOISE GENERATOR, Measurement techniques, 39(7), 1996, pp. 759-764
The temperature distribution in the waveguide channel of a millimeter-
band thermal noise generator is calculated. It is shown that, under ce
rtain conditions, it is governed solely by the temperature-dependence
of the thermal conductivity of the waveguide material. The calculated
distribution enables the error due to the uncertainty in this distribu
tion to be reduced by 20-30%.
