ABSTRACT:
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.
