Hyperfrequency oscillator operating in the millimetric band
First Claim
1. Hyperfrequency oscillator, operating in the millimetric band, comprising a wave guide closed at a first end by an iris diaphragm and by a useful load impedance and at a second end by a supplementary load impedance and also comprising a negative resistance semiconductor element, electrically polarized by means of an aerial that couples the semiconductor element to the waveguide, said oscillator further comprising a resonator cavity, in the waveguide, delimited by the iris diaphragm and by a dielectric resonator placed in the waveguide at a location between the aerial that couples the semiconductor element and the supplementary load.

Abstract
The invention concerns a negative resistance hyperfrequency oscillator, operating in the millimetric band, comprising a waveguide delimited on one side by an iris and a useful load and on the other side by a supplementary load, wherein a Gunn or Impatt diode is polarized and coupled to the waveguide by means of an aerial, the resonator cavity of this oscillator being delimited by the iris and by a dielectric resonator placed in the waveguide between the aerial and the supplementary load, and double coupling being provided between the resonator and the guide and between the diode to the guide to produce a stable and relatively noiseless oscillator. The invention can be applied to hyperfrequency systems, for synchronizing hyperfrequency sources and conjugating their power.
