Patent ID: 7656250

Claim:
A termination block for coupling signal devices, the block comprising: a housing defining an enclosed space; a first pair of connectors connected to the housing for coupling to a first signal device; a second pair of connectors connected to the housing for coupling to a second signal device; a biasing connector connected to the housing; and an electrical circuit comprised of: first and second conductive paths, each conductive path including conductors and electronic elements that electrically connect one of the first pair of connectors to one of the second pair of connectors, a third conductive path electrically connecting the first and second conductive paths, a fourth conductive path electrically connecting the biasing connector to the third conductive path, wherein the electrical circuit provides impedance matching between a first signal device connected to at least one of the first pair of connectors and a second signal device connected to at least one of the second pair of connectors; wherein the circuit is fixedly secured within the enclosed space and is symmetrical about a central plane passing midway between the first and second pair of connectors.
