HIGH FREQUENCY HELICAL AMPLIFIER AND OSCILLATOR

摘要

Disclosed herein is a class of mm and sub mm wavelength amplifiers and os cillators operating with miniature helical slow wave circuits manufactured u sing micro fabrication technology. The helices are supported by diamond diel ectric support rods. Diamond is the best possible thermal conductor, and it can be bonded to the helix. The electron beam is transmitted, not through th e center of the helix, but around the outside. In some configurations the RF power produced may be radiated directly from the slow wave circuit. The met hod of fabrication, which is applicable above 60 GHz, is compatible with mas s production.
