Abstract
A broadband, high power balun which includes plural sets of first and second coaxial cables. Each cable has a center conductor and a shield conductor. Each shield conductor of each cable within each set is connected to a shield conductor of the other coaxial cable of the set. The first input lead is connected to a first end of a center conductor of a first coaxial cable of each set. The second input lead is connected to a first end of a center conductor of a second coaxial cable of each set. A second end of a center conductor of a first coaxial cable of a set of coaxial cables provides an output lead for the balun. A second end of a center conductor of a second coaxial cable of a set of coaxial cables provides an output lead for the balun. A second end of each remaining center conductor of each coaxial cable of each set of coaxial cables is connected to a second end of a center conductor of a coaxial cable of another set of coaxial cables. The inventive balun design allows for larger center conductors and lower characteristic impedances than conventional baluns. This permits impedance matching across a broad bandwidth at high power levels.
