  • Nanometer Electromechanical Switch and Fabrication Process
    Publication number: 20070229199
    Abstract: The present invention describes nano-scale fabrication technique used to create a sub-micron wide gap across the center conductor of a coplanar waveguide transmission line configured in a fixed-fixed beam arrangement, resulting in a pair of opposing cantilever beams that comprise an electro-mechanical switch. Accordingly, a nanometer-scale mechanical switch with very high switching speed and low actuation voltage has been developed. This switch is intended primarily for application in the RF/microwave/wireless industry.

  • Global equivalent circuit modeling system for substrate mounted circuit components incorporating substrate dependent characteristics
    Patent number: 7269810
    Abstract: The present invention is a substrate dependent circuit modeling system for substrate-mounted components. The height and dielectric constant of a substrate have a significant impact on the frequency response of such components, and these effects cannot be treated independently from the circuit model. The equivalent circuit parameters in the model must be made to vary in accordance with changes in the substrate.

  • Microelectromechanical slow-wave phase shifter device and method
    Patent number: 7259641
    Abstract: The present invention provides a method and apparatus for a monolithic device utilizing cascaded, switchable slow-wave CPW sections that are integrated along the length of a planar transmission line. The purpose of the switchable slow-wave CPW sections elements is to enable control of the propagation constant along the transmission line while maintaining a quasi-constant characteristic impedance. The device can be used to produce true time delay phase shifting components in which large amounts of time delay can be achieved without significant variation in the effective characteristic impedance of the transmission line, and thus also the input/output return loss of the component. Additionally, for a particular value of return loss, greater time delay per unit length can be achieved in comparison to tunable capacitance-only delay components.
