Paper Abstract

Small area, low capacitance Schottky barrier diodes are currently available from only two suppliers in the world, and very considerable technological effort is required to obtain stable, low-noise operation when junction capacitances of 1 fF or less are required. Such diodes have been reported in the literature [1], and yield low noise and low conversion loss [2]. As a result of the increasing need for such diodes at frequencies above 500 GHz, and the possible need for tailoring specifications to particular space or radioastronomical requirements, a consortium of four German technical universities and a group of potential users combined to initiate fabrication and measurement of such diodes. This paper reports the first results.
