Design and Performance of a 600-720-GHz Sideband-Separating Receiver Using AlO(x) and AlN SIS Junctions
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011-01)
We present the design, modeling, construction, and characterization of a sideband separating heterodyne receiver that covers the frequency range from 600 to 720 GHz. The receiver has been constructed using waveguide ...
Lumped- and distributed-element equivalent circuits for some symmetrical multiport signal-separation structures
(1997)
This paper presents an extension to the synthesis of the symmetrical analysis methods for modeling passive ra-port junctions. Two approaches are discussed: the electrical one based on consideration of even- and odd-propagation ...
