ABSTRACT:
A short slot waveguide hybrid coupler is disclosed wherein the coupling factor is switchable over a predetermined range of discrete coupling factors. A coupling slot formed in the common dividing wall between the contiguous first and second waveguides of the coupler allows coupling of electromagnetic energy between the two waveguides in accordance with a first coupling factor. A plurality of conductive pins are arranged for selective insertion into the coupling slot to effectively shorten the slot and thereby progressively reduce the coupling factor as more pins are inserted into the coupling slot.
