ABSTRACT:
A redundancy combiner assembly has two amplifiers connected in parallel along a waveguide path to a hybrid. The hybrid is connected through a transfer switch to an antenna. The hybrid contains a movable coupling plate. The coupling plate has a coupling array to allow combining of signals of the amplifiers in one position. When one of the amplifiers fails, the coupling plate is replaced by a metal wall and the output from the failed amplifier is directed by the switch to a dump load while the output from the operating amplifier is directed to the antenna. The assembly is controlled by a controller, which monitors the amplifiers and controls the movement of the coupling plate and the switch.
