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.
