  • Patent number: 9007143
    Abstract: An improved implementation of a 2×4 divider formed from a bridge junction is described. The bridge junction uses parallel and series connections of coaxial lines to eliminate impedance transformers that are normally required in a 2×4 power divider. In a preferred embodiment, the bridge junction is comprised of UT-085 coax transmission lines, 20 gauge twin lead wire and SB-805-61 ferrite beads with ½ turn windings to provide a wide bandwidth, compact, high power and rugged arrangement.
    Type: Grant
