PY - 1999 DA - 1999// TI - An 800 GHz NbN phonon-cooled hot-electron bolometer mixer receiver T2 - IEEE Trans. Appl. Supercond. JO - IEEE Trans. Appl. Supercond. SP - 3753 EP - 3756 VL - 9 IS - 2 KW - NbN HEB mixers AB - We describe a heterodyne receiver developed for astronomical applications to operate in the 350 /spl mu/m atmospheric window. The waveguide receiver employs a superconductive NbN phonon-cooled hot-electron bolometer mixer. The double sideband receiver noise temperature closely follows 1 kGHz/sup -1/ across 780-870 GHz, with the intermediate frequency centered at 1.4 GHz. The conversion loss is about 15 dB. The receiver was installed for operation at the University of Arizona/Max Planck Institute for Radio Astronomy Submillimeter Telescope facility. The instrument was successfully used to conduct test observations of a number of celestial sources in a number of astronomically important spectral lines.
