ABSTRACT:
The specification describes a means and method for mixing millimeter wave RF energy of one chosen transverse electric (TE) waveguide mode with a local oscillator signal of another chosen TE waveguide mode, and such mixing is accomplished by applying those RF and local oscillator signals to a pair of reverse poled and parallel connected mixer diodes. These mixer diodes are connected at a chosen location within a rectangular waveguide and between top and bottom walls thereof and are symmetrically spaced across the width of the waveguide with respect to the center or a/2 location in the guide, with "a" being the width dimension in the guide. An IF output signal is derived at a common output node for the mixer diodes.
