Noise analysis in bolometer detector for microwave power measurements.
A study of noise related with a thermal detector used as power standard on the 26.5-40GHz frequency band, is presented. This study starts with electromagnetic and thermal analysis, and is based on a cryogenic resistive thermometer functioning at liquid-He temperatures. In addition, the study fixes the theoretical limit of sensitivity.
