ABSTRACT:
A splitter/combiner system including directional couplers and phase shifts where some of the directional couplers are subdivided into shorter directional couplers, with 0° phase shifts between them. The system provides improved ease of design, and uniformity. The subdivided couplers also provide more accurate ratios between all the couplers in the splitter/combiner.
