    Abstract: Pilot switch circuitry grounds a hot node (an injection node) of a microelectromechanical system (MEMS) switch to reduce or eliminate arcing between a cantilever contact and a terminal contact when the MEMS switch is opened or closed. The pilot switch circuitry grounds the hot node prior to, during, and after the cantilever contact and terminal contact of the MEMS come into contact with one another (when the MEMS switch is closed). Additionally, the pilot switch circuitry grounds the hot node prior to, during, and after the cantilever contact and terminal contact of the MEMS disengage from one another (when the MEMS switch is opened).

    Abstract: A method for manufacturing a micro electro-mechanical system (MEMS) switch system (600, 700) includes etching each of a plurality of base circuit layers (425) and a plurality of passive component substrate layers (412, 418, 42, 426). The method continues with laser milling of a first dielectric film (406) to create a spacer layer (405). A metal cladding (402, 403) formed on a flexible dielectric film layer 404 is etched so as to form a plurality of switch component features. Further laser milling is performed with respect to the flexible dielectric film layer to form at least one switch structure (448, 450). Thereafter, a stack (400) is assembled which is comprised of the spacer layer disposed between the flexible dielectric film layer and the plurality of base circuit layers. Additional layers can also be included in the stack. When the stack is completed, heat and pressure are applied to join the various layers forming the stack.

    Abstract: A representative embodiment of the invention provides a thermal actuator for a MEMS-based relay switch. The thermal actuator has an “active” arm that is movably mounted on a substrate. The “active” arm has (i) a thermal expansion layer and (ii) a resistive heater that is electrically isolated from the thermal expansion layer. The thermal expansion layer is adapted to expand in response to a temperature change induced by a control current flowing through the resistive heater, thereby bending the “active” arm and moving that arm with respect to the substrate. Due to the fact that mechanical and electrical characteristics of the “active” arm are primarily controlled by the thermal expansion layer and the resistive heater, respectively, those characteristics can be optimized independently to obtain better operating characteristics for MEMS-based relay switches of the invention compared to those attained in the prior art.

    Abstract: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.
