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.
Claims4
A negative-resistance microwave circuit comprising one wave-guide and at least a pair of chambers (22,23) with conductive walls forming a symmetrical arrangement in the right section plane (21) of said wave-guide, each chamber communicating with said wave-guide, and containing means (28, 29, 30) for supporting and polarizing a negative-resistance diode (26,27), said polarizing means forming with the walls of each chamber a coaxial line portion.
