A basic reflector arrangement has first and second power splitters. Each power
splitter has first to fourth ports where the first port of the first power splitter
is coupled to a remote signal source for receiving signals therefrom and providing
feedback signals thereto. Signals received at each of the first and fourth ports
of each power splitter are combined and split into first and second portions for
transmission via the second and third ports, respectively, and signals received
at the second and third ports are combined and split into first and second portions
for transmission via the first and fourth ports, respectively. The second port
of the second power splitter is coupled to provide an output signal from the reflector
arrangement, and the first, third, and fourth ports thereof are coupled to the
second, third, and fourth ports, respectively, of the first power splitter.
