Abstract
This invention is a broadband matrix switch system and method of operation. The broadband matrix switch has N number of broadband inputs, each of the broadband inputs having one or more broadband signals. The matrix switch has M number of broadband outputs. There are N number of splitters. Each of the splitters has a splitter input connected to one of the broadband inputs. Each of the splitters has M number of splitter outputs that produce the splitter output signal. There are N times M number of node switches. Each node switch is uniquely connected to one of the splitter outputs. The node switches have a control input that allows the node switch to pass the respective splitter output signal upon receiving a close command at the control input and to terminate the respective splitter output signal with an input impedance upon receiving an open command at the control input. There are M number of combiners. Each combiner has a combiner output connected to one of the broadband outputs. Each combiner further having N number of combiner inputs. Each of the combiner inputs are connected to one and only one of the inputs through the respective splitter and node switch. The node switches te…
