ABSTRACT:
A redundant microwave switching matrix providing equal power distribution of any of a plurality of microwave input signals among one or more of a plurality of microwave output signals. The redundant switching matrix used in a communication satellite selectively couples one or more of a plurality of input microwave signals received by receiving antennas among one or more of a plurality of output microwave signals radiated by transmitting antennas. The means for coupling the input and output microwave signals is provided by a pair of directional couplers diametrically positioned at each coordinate of the switching matrix. A controller selectively enables a pair of PIN diodes, internally positioned within each directional coupler, to perform the desired coupling. Diametrically positioned directional couplers, having a pair of PIN diodes, provide a highly reliable and flexibility microwave switching matrix.
