Abstract :
Based on a one dimensional heat transport equation for the electrons in a superconducting hot electron bolometer, a model for a hot spot mixer is set up. The heating due to a DC bias is limited to the hot spot region where the LO power is absorbed uniformly. This gives rise to a novel measurement method for the absorbed LO power
