Paper Abstract

GaAs Schottky barrier mixer diodes have been successfully used in heterodyne receivers throughout the millimeter and submillimeter wavelength ranges [1,2]. These receivers combine excellent spectral resolution (∆ν/ν=10-6) and exceptional sensitivity, and have given scientists an important tool for use in such fields as radio astronomy [3], atmospheric studies [4], chemical spectroscopy [5] and plasma diagnostics [6]. Although superconducting devices (SIS junctions) have recently achieved better performance at millimeter wavelengths [7], it is not certain when, or if, SIS technology will be extended to terahertz frequencies. Since there are a great many scientific programs which rely on submillimeter wavelength heterodyne technology, including studies of ozone depletion [8] and space based astronomy [9], it is critical that the Schottky technology be pushed to its fundamental limits.
