  • Abstract
    We have demostrated the use of cryogenic variable-temperature loads for accurate noise measurements of low-noise cooled amplifiers and mixers in the microwave and millimeter wave range. The input noise temperature of the amplifier or mixer can be measured with an accuracy of ± 1 K or better.
