Schottky diode-based terahertz frequency multipliers and mixers

Abstract This article presents some aspects of the technology of terahertz heterodyne receiver front-ends dedicated to astrophysics, planetary and atmospheric sciences. It focuses on frequency multipliers and on Schottky mixers. Novel architectures of power-combined frequency multipliers at submillimeter-wavelengths, THz planar fundamental mixers, and integrated receivers will be discussed, as well as the fabrication of submillimeter-wave planar Schottky diodes in France.
