Integration of silicon-based MMIC technology for millimeter wave cryogenic receivers.

Ramírez Ortega, Wagner Esteban (Universidad de Concepción.Departamento de Ingeniería EléctricaDepartamento de Ingeniería Eléctrica., 2021)

This thesis work is framed in the area of astronomical instrumentation, specifically regarding the frequency range of millimeter wave. The demand for efficiency in the astronomical observations of low noise requires the ...

ALMA band 1 optics (35-50 GHz): tolerance analysis, effect of cryostat infrared filters and cold beam measurements

González, A.; Tapia, V.; Finger Camus, Ricardo; Huang, C. D.; Asayama, S.; Huang, Y. D. (Springer, 2017)

The Atacama Large Millimeter/Sub-millimeter Array (ALMA) is currently the largest (sub-)mm wave telescope in the world and will be used for astronomical observations in all atmospheric windows from 35 to 950 GHz when ...

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 ...
