Abstract: A switch device may comprise a micro-relay disposed between a first terminal and a second terminal. The micro-relay may be configured to selectively electrically couple the first terminal to the second terminal. The switch device may further comprise a bypass circuit configured to selectively divert at least a portion of electrical current flowing from the first terminal to the micro-relay, and direct the diverted electrical current to the second terminal. The switch device may further comprise an energy harvesting circuit configured to (i) withdraw a portion of energy flowing into the switch device, (ii) store the portion of energy in an energy storage device, and (iii) supplying the energy stored in the energy storage device to one or more components within the switch device.

Abstract: A device for switching a differential signal includes an input port, a first output port, a second output port, a first micro electromechanical system (MEMS) switch, and a second MEMS switch. The first and second MEMS switches selectively couple the input port to either the first output port or the second output port. The differential input port is separated into two single-ended paths. One single-ended path is switched through the first MEMS switch, and the other single-ended path is switched through the second MEMS switch. The single-ended paths are spatially matched with respect to length and orientation, and are at least partially distributed through at least two layers of electrical conductors, with adjacent layers of electrical conductors separated by electrically insulating layers.
