Abstract
A multi-port amplifier system for multi-beam communication antennas in which redundancy is achieved without using RF switches. The multi-port amplifiers are divided into sets of stages arranged in tree fashion and the amplifier stages can be turned off without degrading port-to-port isolation. In one embodiment there are thirty-two input ports 1 through 32 and thirty-two corresponding output ports 1 through 32 wherein input port 1 is functionally connected to output port 1 and so on. An input signal to each of the input ports 1 through 32 is connected to a separate one of a first group of sixteen, four stage multi-port hybrid circuits. The outputs of the first group of multi-port hybrid circuits are connected through solid-state power amplifiers to a second group of sixteen, four stage multi-port hybrid circuits which are also labeled according to the input port numbers to which they are functionally connected.
