1. A power combiner for microwave energy, comprising:

  • a housing having at least one internal cavity disposed therein defined by a pair of facing end surfaces, said internal cavity being sized to resonate at a single frequency;

    diode means situated within said housing for providing a source of microwave energy;

    diode waveguide means positioned to extend radially within said housing, and having a coupling point situated axially adjacent one end surface defining said internal cavity, for electrically coupling said diode means to said internal cavity;

    aperture means disposed through one of said end surfaces defining said internal cavity, near the periphery thereof, and situated in axial alignment with said coupling point of said radial waveguide means for forming an opening to said internal cavity through which microwave energy can propagate;

    output means including an axially extending waveguide through one of said end surfaces defining said internal cavity for propagating microwave energy out of said power combiner; and

    means including an axially extending waveguide through the other one of said end surfaces for reflecting microwave energy back into said cavity.
