Abstract
Abstract A microwave oscillator in which the power supplied by 2N microwave diodes such as avalanche or Gunn effect diodes is added. The diodes are connected together in two by sections of strip lines which enables magnetic coupling between these diodes and a dielectric resonator, with the diodes in each couple operating in phase opposition.
