A compact waveguide power combiner/divider is characterized by low reflection and dissipation losses. The device includes a radial waveguide having an inlet opening and a plurality of radial outlet openings, and a coupling pin is arranged in the radial waveguide to couple energy from the inlet opening with the radial waveguide. A mode suppression device is connected with the radial waveguide and contains a plurality of radially arranged slots corresponding with the outlet openings. A tuning mechanism arranged within the radial waveguide optimizes the coupling of undesired modes with the slots. An undesired mode absorption device is arranged in cooperation with the slots of the mode suppression device so that undesired modes are isolated from desired modes with low reflection and dissipation losses.
