Abstract

It has been proven that noise temperatures of contemporary cryogenically cooled receivers in mm and submrn wavelengths tend toward the fundamental limits due to the decreased contribution of active components, including mixers, amplifiers, etc. The contributions of passive waveguides therefore become more valuable, and they must be calculated with the consideration of a range of various temperatures.
