Abstract
RF signals may be split or combined across a wide band of frequencies with low insertion losses, large isolation between input ports, and low voltage standing wave ratio by means of coaxial transmission line sections interconnected in a bridge configuration. Even mode impedances between the cable shield and the common ground plane may be eliminated by placing ferrite sleeves on each line section. Impedance transformations introduced by the splitter/combiner are counteracted by a coaxial line impedance transformer.
