  • Tunable RF devices with metallized non-metallic bodies
    Patent number: 6724280
    Abstract: An electronic device comprises a non-metallic waveguide, a tunable component mounted within the waveguide, and a conductive layer on a surface of the waveguide. The tunable component can comprise a tunable filter. The non-metallic waveguide can comprise a plastic material. Connections for applying a tuning voltage to the tunable component can be provided. A temperature sensor can be connected to the waveguide.
    Type: Grant

  • Switched charge voltage driver and method for applying voltage to tunable dielectric devices
    Patent number: 6535076
    Abstract: A circuit for providing a control voltage for tunable dielectric devices, the circuit comprising an input for receiving a voltage command signal, a charging circuit for establishing a desired voltage level on a first capacitor in response to the voltage command signal, and a switch for switching voltage on the first capacitor to a tunable dielectric device to control a dielectric constant of tunable dielectric material in the tunable dielectric device. A second capacitor, second charging circuit, and second switch can be used to provide voltage to the tunable dielectric device during charging or discharging of the first capacitor. The method for providing a control voltage for tunable dielectric devices performed by these circuits is also included.
