Abstract:
A four-way power combiner/splitter, comprising:a first transmission line including a first non-grounding conductor and a first grounding conductor, wherein said first grounding conductor is grounded at a first end of said first transmission line; a second transmission line including a second non-grounding conductor and a second grounding conductor, wherein said second grounding conductor is grounded at a first end of said second transmission line, and further wherein said first and second non-grounding conductors are electrically coupled together at respective first ends of said first and second transmission lines, wherein said first and second transmission lines have substantially the same electrical lengths extending from respective first ends to respective second ends, and wherein said lengths of said first and second transmission lines extending from respective first ends to respective second ends are each less than a quarter wavelength at an operating frequency; an output/input port electrically coupled to said first and second non-grounding conductor at respective first ends of said first and second transmission lines; a first input/output port electrically coupled to said first non-grounding conductor at a second end of said first transmission line; a second input/output port electrically coupled to said first grounding conductor at said second end of said first transmission line; a third input/output port electrically coupled to said second non-grounding conductor at a second end of said second transmission line; and a fourth input/output port electrically coupled to said second grounding conductor at a second end of said second transmission line.
