A high performance 650-GHz sideband separating mixer design and results
(IEEE Inst Electrical and Electronic Engineering Inc., 2017)
We presented the design and experimental results of a new sideband-separating (2SB) mixer for 600-720 GHz (ALMA Band 9). Although designed following the classical quadrature hybrid architecture, the emphasis of the ...
First Supra-THz Heterodyne Array Receivers for Astronomy With the SOFIA Observatory
(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 ...
Modular 2SB SIS Receiver for 600-720 GHz: Performance and Characterization Methods
(IEEE, 2017)
A modular sideband-separating (2SB) receiver for 600-720 GHz has been built and tested. The used modular design allows to characterize all the parts separately, including testing of the superconductor-insulator-superconductor ...
Single-layer dichroic filters for multifrequency receivers at THz Frequencies
(IEEE, 2020)
In this work, we report the design, construction, and characterization of two free-standing single-layer frequency-selective surface structures to be used as dichroic filters in the THz range. Their spectral responses are ...
Development of microwave devices for millimeter and sub-millimeter receivers
(Universidad de Chile, 2017)
The Atacama Large Millimeter/Submillimeter Array (ALMA) is one of the largest astronomical facilities in the world. Each of the 66 antenn as accommo dates ten ob servational band s,
covering from 35-950 GHz. To extend the ...
