  • Tunable micro electromechanical inductor
    Patent number: 7741936
    Abstract: The present invention provides a monolithic inductor developed using radio frequency micro electromechanical (RF MEMS) techniques. In a particular embodiment of the present invention, a tunable radio frequency microelectromechanical inductor includes a coplanar waveguide and a direct current actuatable contact switch positioned to vary the effective width of a narrow inductive section of the center conductor of the CPW line upon actuation the DC contact switch. In a specific embodiment of the present invention, the direct current actuatable contact switch is a diamond air-bridge integrated on an alumina substrate to realize an RF switch in the CPW and microstrip topology.
