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).
