We report on the use of a superconducting hot-electron bolometer mixer for heterodyne detection of terahertz radiation. Radiation with a wavelength of 119 mu m was coupled to the mixer, a NbN microbridge, by a hybrid quasioptical antenna consisting of an extended hyperhemispherical lens and a planar logarithmic spiral antenna. We found, at an intermediate frequency of 1.5 GHz, a system double side band noise temperature of approximate to 40 000 K and conversion losses of 25 dB. We also discuss the possibilities of further improvement of the mixer performance. (C) 1996 American Institute of Physics.
