A detector of microwave radiation includes a signal input and a detector output. An absorber element of ohmic conductivity is coupled to said signal input through a first length of superconductor. A variable impedance element, the impedance of which is configured to change as a function of temperature, is coupled to the detector output through a second length of superconductor. The detector also includes a heating input and a heating element coupled to the heating input through a third length of superconductor. The absorber element, the variable impedance element, and the heating element are coupled to each other through superconductor sections of lengths shorter than any of said first, second, and third lengths of superconductor.
