A method of mitigating self-actuation of a switch may comprise generating a tracking signal, based on an input signal that the switch is configured to convey, and combining the tracking signal with an actuating signal to generate a modified actuating signal. The actuating signal may be configured to change a state of the switch from a first state (e.g., ON) to a second state (e.g., OFF). The method further comprises selectively applying the modified actuating signal to a gate of the switch. A switch self-actuation mitigation system may comprise a first coupling device for electrically couple an AC component of a first signal to a node, where the first signal is applied a switch input. The system may further comprise a second coupling device configured to electrically couple an actuating signal to the node, and a driving device configured to selectively couple the node to a gate of the switch.

A microwave branching switch for selectively interconnecting terminals of a plurality of microwave transmission lines, involving microwave transmission lines with a terminal; a housing in which the terminals are arranged; a switching portion with a junction portion for selectively interconnecting terminals of the microwave transmission lines through selective interconnection. The switching portion is switchable between a first position and a second position; wherein the switching portion with the junction portion is dimensioned and positioned inside the housing in dependence of an arrangement of the microwave transmission lines such that the junction portion interconnects a first group of terminals when the switching portion is in the first position and interconnects a second group of terminals when the switching portion is in the second position. The first and second groups of terminals differ in at least one terminal and the first group of terminals involves at least three terminals.

One embodiment of the invention includes a phase-change material switch. The switch includes a first terminal that receives an input signal and a second terminal. The switch includes an actuation portion that receives a control signal in one of a first state to emit a first heat profile and a second state to emit a second heat profile. The switch further includes a switch portion comprising a phase-change material arranged as a plurality of longitudinal strips that each interconnect the first terminal and the second terminal and that are each in proximity with the actuation portion. The phase-change material can be selectable between a conducting state in response to the first heat profile to conduct an input signal from the first terminal to the second terminal and a blocking state in response to the second heat profile to block the input signal from the first terminal to the second terminal.

An RF crossover apparatus provides low transmission and return losses for microwave systems and meets the requirement for the RF signals to leap over each other as in an insulated state. The RF crossover apparatus contains a body produced from ceramic material, at least two RF strips placed inside the body in a way to intersect each other and at least one insulation layer insulating the RF strips placed on the body at least from the external environment. The body produced from ceramic material enables operation on high frequencies and this provides low transmission and return losses. The RF crossover apparatus also contains matching circuits on the tips of the RF strips for the RF strips to be passed to chip devices during use.

A non-contact type coaxial switch that eliminates all contacts and inner conductors. The switch includes a stator/coax base assembly and a rotor. The stator/coax base assembly is fixed, while the rotor is rotatably mounted to the stator/coax base assembly and eliminates all contacts and inner conductors. The rotor is disposed between bearings, and consists of waveguide paths that couple between selected coax connectors. When the rotor is rotated, different selected coax connectors occur. For other arrangements selected, the rotor can switch between a condition of coax and waveguide outputs. The rotor, between bearings, consists of waveguide paths which couple between selected coax connectors. When the rotor is rotated, a different selected coax connector occurs. For other arrangements selected, the rotor can switch between a combination of coax and waveguide outputs.
