Abstract
Active switch matrix apparatus that is used in a satellite communications system that provides for reconfigurability of the communication channels of the communications system. The active switch matrix apparatus has redundan channels and components that provides for a high probability of success during the lifetime of the satellite. The active switch matrix apparatus is comprised of two switch matrices, one for each polarization (horizontal and vertical). Each of the switch matrices contains redundancy, including redundant paths through power dividers, power combiners and amplifiers to outputs of the apparatus. This is accomplished using a plurality of controllable switches in the power dividers and a plurality of controllable output switches coupled to outputs of the amplifiers. Each of the switch matrices are coupled to redundant DC/DC converters and switch matrix controllers.
