ABSTRACT:
A compact inline waveguide power divider is provided that comprises a primary waveguide in communication with two parallel waveguides. The two parallel waveguides are stacked on top of one another and each parallel waveguide further comprises an output port. Accordingly, an input signal is transmitted through the primary waveguide and split between the two parallel waveguides. A resistive slot is formed in each of the parallel waveguides, thereby increasing output port isolation through dissipation of reflected power from one output port to the other. Further, a stepped or tapered impedance transformation is applied in each parallel waveguide to provide wide band frequency matching. Alternately, the primary waveguide and the parallel waveguides may be configured as a waveguide power combiner rather than a divider, wherein the parallel waveguides comprise input ports and the primary waveguide comprises an output port.
