ABSTRACT:
A network is disclosed for distributing a signal from a single source (18) to each of 2.sup.n (20.sub.1, 20.sub.2 . . . 20.sub.2n where n is an integer, such that the signals supplied to the loads each have substantially the same phase and amplitude. The network comprises 2.sup.n paths (22.sub.1, 22.sub.2 . . . 22.sub.2n), each coupling the source to a separate one of the loads. Each path is comprised of 2n+1 serially coupled segments 24.sub.1, 24.sub.4 . . . 24.sub.2n+1) with 2n-1 of the segments (24.sub.1, 24.sub.4 . . . 24.sub.2n-1) of each branch being common to another path. The segments in each path have corresponding impedances (Z.sub.1, Z.sub.2 . . . Z.sub.2n+1), respectively, which are selected so that each load is substantially matched to the source and that the internal reflection of the signals within each path is minimized.
