Abstract
An M by N switch matrix includes N input switches each single-pole M-throw, M output switches each N-throw single-pole with the N*M outputs of the N input switches coupled directly to respective ones of the N*M inputs of the M output switches whereby a signal applied at any of the N input switches can be coupled to the output of any one of the M output switches. The switches may consist of a plurality of dual-gate field effect transistors enabling the switching matrix to be utilized at microwave frequencies.
Claims12
An M by N signal switching matrix for coupling various ones of N input lines to various ones of M output lines comprising in combination:
- N single-pole, M-throw input switches coupled to said N input lines where each of said switches has M outputs;
- M N-throw, single-pole output switches coupled to said M output lines where each of said output switches has N inputs;
- M*N connections between respective ones of the M outputs of the N input switches and respective ones of N inputs to the M output switches where M and N are integers, M<=>N and * is the multiplication symbol.
