1. A microwave transition device for coupling a waveguide and a microwave integrated circuit, said transition device being located within said waveguide for alignment with an electric field having microwave energy, said device comprising:

  • a dielectric substrate having a metallized surface on only one side thereof;

    a unilateral finline formed in said metallized surface at an end portion of said substrate;

    a slotline formed adjacent to said finline on said metallized surface and connected to said finline at one end thereof; and

    a balun positioned proximate to said slotline, said microwave integrated circuit being attached to said metallized surface and connected to said balun, wherein said balun comprises a portion of said slotline equal in length to 1/4 of the wavelength of the electric field and a wire bond, passing over said portion of said slotline, and connected at one end to said microwave integrated circuit and at an opposite end to said metallized surface.
