ABSTRACT:
Disclosed is a solid state power source which combines the power of a plurality of negative resistance transistor packages in a circular cavity to form an oscillator producing a resonant source of microwave energy for radar or microwave energy oven applications. The power of the plurality of negative resistance transistor packages is fed to the cavity through a plurality of gapped coaxial cable antennae selectively positioned adjacent the circular cavity wall. The antennae terminate in an microwave energy termination and dc base biasing circuitry.
