Abstract:
1. A 2×2 switching element for routing analog signals, comprising: a first relay comprising a first terminal, a second terminal and a third terminal, wherein the first relay is configured to selectively operate between a first state configured to connect the first terminal of the first relay to the second terminal of the first relay and a second state configured to connect the first terminal of the first relay to the third terminal of the first relay; and a second relay comprising a first terminal, a second terminal and a third terminal, wherein the second relay is configured to selectively operate between a third state configured to connect the first terminal of the second relay to the second terminal of the second relay and a fourth state configured to connect the first terminal of the second relay to the third terminal of the second relay; wherein the first relay is disposed on a first face of a printed circuit board (PCB) and the second relay is disposed on a second face of the PCB that is opposite from the first face; wherein the second terminals of the first and second relays are coupled to one another, and comprise or are coupled to an input terminal of the 2×2 switching element configured to receive the analog signals; wherein the third terminals of the first and second relays are coupled to one another, and comprise or are coupled to an output terminal of the 2×2 switching element configured to output the analog signals; and wherein the 2×2 switching element is selectively operable between:
