Abstract:
1. A radio frequency (RF) signal combiner/splitter comprising: a printed circuit board (PCB) having first and second opposing major surfaces, and a plurality of openings therethrough; and a ferromagnetic body comprising a first portion spaced from the first major surface of said PCB, a second portion spaced from the second major surface of said PCB, and a plurality of interconnecting portions coupling said first and second portions and extending through respective openings in said PCB; said PCB comprising a substrate and conductive traces thereon in a laterally extending spiral pattern on said substrate and cooperating with said ferromagnetic body to define circuitry for combining/splitting RF signals, said circuitry for combining/splitting RF signals comprising a plurality of summing toroidal inductors based upon said ferromagnetic body and said conductive traces.
