Hot-electron bolometer terahertz mixers for the Herschel Space Observatory.
We report on low noise terahertz mixers (1.4-1.9 THz) developed for the heterodyne spectrometer onboard the Herschel Space Observatory. The mixers employ double slot antenna integratedExpand

Conversion gain and noise of niobium superconducting hot-electron-mixers
A study has been done of microwave mixing at 20 GHz using the nonlinear (power dependent) resistance of thin niobium strips in the resistive state. Our experiments give evidence that electron-heatingExpand

1.6 THz heterodyne receiver for the far infrared space telescope
Abstract A low noise heterodyne receiver is being developed for the terahertz range using a phonon-cooled hot-electron bolometric mixer based on 3.5 nm thick superconducting NbN film. In the 1–2 GHzExpand
