TLDR
Schottky diodes have been used for the first time as harmonic mixers in the 0.1-1.0mm wavelength region as discussed by the authors, where the beat notes between the 33rd harmonic of a 74 GHz V-band klystron and 118.8μ laser radiation are observed directly without the need of narrow-band synchronous detection.Abstract:
Schottky diodes have been used for the first time as harmonic mixers in the 0.1–1.0‐mm wavelength region. Beat notes between the 33rd harmonic of a 74‐GHz V‐band klystron and 118.8‐μ laser radiation are observed directly without the need of narrow‐band synchronous detection. The demonstrated performance of these room‐temperature diodes as wide‐band or heterodyne detectors of submillimeter radiation and their rugged construction make them superior to current point contact devices.read more

Quantum limited detection in tunnel junction mixers
TL;DR: In this article, a complete quantum generalization of microwave mixer theory is constructed for nonlinear single-particle tunnel junctions, which represents a unification of the concepts used to describe these "classical" resistive mixers with the language of photon detection.
