Abstract
A circuit for microwave oscillators or amplifiers, yielding the maximum microwave power from negative resistance diodes feeding into one and the same waveguide section. Diodes are arranged in pairs symmetrically at the level of one and the same right section of the waveguide but outside the waveguide cavity. In the case where two diodes are used, these are screwed into clamps arranged in chambers opening into the cavity. Cylinders effect impedance matching between waveguides and diodes and are supported mechanically by a shaft which supplies the direct voltage for the circuit.
