HYPERFREQUENCY OSCILLATOR WITH VERY HIGH STABILITY

摘要

The invention relates to an oscillator, characterised in comprising a monobloc dielectric resonator in the form of a straight cylindrical section, hollowed in the mid-section thereof along the chords of the straight section thereof, such as to leave a central core and two lateral faces. The hollows have a symmetry of order N with N = 4, at least the planar faces of the cylinder are covered with a superconducting material, the resonator being placed in a cryogenic bath and connected to an amplifier by optimum means. The resonator connection is made by means of magnetic field and phase loop.
