ABSTRACT:
A signal splitter connects a radio frequency signal source to a pair of output loads, e.g., separate receivers, and has an increased high-end frequency response as compared to similar devices. First and second tubular cores are disposed side by side, each with a pair of toroidal windings therein. An input end of the first winding of the first core is coupled to the signal input and the second end of the second winding to ground, respectively, while output ends of the windings in the second core are connected to the output loads. The other ends of the windings of the two cores are respectively connected to one another to form two single-pair twisted connections. These are passed into through holes of a printed circuit board and are soldered or otherwise electrically connected to a printed conductor on the board. This construction reduces stray inductance significantly and also provides better mechanical mounting than previous devices. The two tubular cores could be fused as a single core with two holes.
