Abstract: The paper discusses the hot-spot model of the superconducting hot-electron bolometer applied to the estimation of the absorbed local oscillator power. As the length of the sensitive element is decreased the absorbed power becomes length-independent. 

Key words: hot-electron effect in superconductors, heterodyne receivers, absorbed local oscillator power.
