ABSTRACT:
An N.times.M signal routing matrix has low loss. The N input ports are connected to N input transmission lines, and the M output ports are connected to M output transmission lines. A plurality of interconnects interconnect the input and output transmission lines at their crossing points. The points of connection of the interconnects to any one of the input or output transmission lines are spaced .lambda./2 (or multiples thereof) apart along the transmission line. Each interconnect includes a transmission line at least .lambda./2 long, and each includes a short-circuiting switch arrangement capable of short-circuiting the inteconnecting transmission line at point(s) .lambda./4 (or odd multiples thereof) from the ends of the interconnecting transmission line. In order to form a path for the flow of signal between a selected input port and a selected output port, the switching arrangement of that one interconnect which interconnects the input and output transmission lines corresponding to the selected ports is not short-circuited, and all other switching arrangements of interconnects terminating on one of the corresponding transmission lines are short-circuited. In some embodiments, multiple independent signal paths are available. In some embodiments, redundant paths are provided.
