Abstract
The performance of heterodyne receivers for frequencies beyond 1.4 THz will be reviewed. Emphasis will be on the development of the 4.7-THz frequency channel for the GREAT heterodyne spectrometer on SOFIA. This receiver is based on a phonon-cooled hot-electron bolometric mixer and a quantum-cascade laser as local oscillator.
