Abstract: A switching system includes a MEMS switching circuit having a MEMS switch and a driver circuit, and an auxiliary circuit coupled in parallel with the MEMS switching circuit that comprises solid state switching circuitry. A control circuit in communication with the MEMS switching circuit and the auxiliary circuit performs selective switching of a load current towards the MEMS switching circuitry and the auxiliary circuit, with the control circuit programmed to transmit a control signal to the driver circuit to cause the MEMS switch to actuate to an open or closed position across a switching interval, activate the auxiliary circuit during the switching interval when the MEMS switch is switching between the open and closed positions, and deactivate the auxiliary circuit upon reaching the open or closed position after completion of the switching interval, such that the load current selectively flows through the MEMS switch and the solid state switching circuitry.

Abstract: An ohmic RF MEMS relay includes a substrate with a capacitive coupling, Csub; two actuating elements electrically coupled in series, so as to define a channel, wherein the actuating elements are configured to be independently actuated or simultaneously operated. The actuating elements have their own capacitive coupling, Cgap; a midpoint on the channel is in electrical communication with the actuating elements; and an anchor mechanically coupled to the substrate and supporting at least one of the actuating elements. Also, an ohmic RF MEMS relay that includes an input port; a plurality of first MEMS switches that make up a first switching group in electrical communication with the input port, thereby defining a plurality of channels each leading from each of the MEMS switches; and at least one outlet port along each of the channels distal from the first switching group and in electrical communication with the input port.
