    • A cryogenic solid state LO source at 1.9THz 
      Reyes Guzmán, Nicolás; Güsten, Rolf; Graf, Urs; Risacher, Christophe; Ricken, Oliver (ISSTT, 2017)
      The Low Frequency Array instrument at SOFIA is a heterodyne array designed to observe in the complete range between 1.9 and 2.5 THz. It is a 14 pixel instrument, working in a dual polarization configuration. To provide ...
    • First Supra-THz Heterodyne Array Receivers for Astronomy With the SOFIA Observatory 
      Risacher, Christophe; Guesten, Rolf; Stutzki, Juergen; Huebers, Heinz Wilhelm; Buechel, Denis; Graf, Urs U.; Heyminck, Stefan; Honingh, Cornelia E.; Jacobs, Karl; Klein, Bernd; Klein, Thomas; Leinz, Christian; Puetz, Patrick; Reyes Guzmán, Nicolás Andrés; Ricken, Oliver; Wunsch, Hans Joachim; Fusco, Paul; Rosner, Stefan (IEEE-Inst Electrical Electronics Engineers Inc, 2016)
      We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The low-frequency array (LFA) is designed to cover the 1.9-2.5 THz range using 2 7-pixel wave-guide-based HEB mixer arrays in a dual polarization ...
