Abstract

A radio frequency network, comprises a first common node (2) connected to a common input or output port (8), a second common node (3), and at least three identical branches (1) therebetween, each branch (1) comprising a first branch node (4), to which is connected a balance load (6), and a second branch node (5) spaced therefrom and connected to a branch output or input port (7), the network being dimensioned and arranged such that an r.f. signal of a specific frequency input at the common input port (8) is divided equally between all the branch output ports (7), and a plurality of identical r.f. signals of the specific frequency applied in phase to all the branch input ports (7) appear combined at the common output port (8).
