  • Tunable high-frequency capacitor
    Patent number: 6804107
    Abstract: A tunable high-frequency capacitor includes first and second fixed electrodes, the first fixed electrode having a high-frequency input connection, and the second fixed electrode having a high-frequency output connection. A movable electrode is arranged facing and spaced apart from the fixed electrodes and is supported by means of a suspension which causes a displacement of the movable electrode in relation to the fixed electrode depending on a control signal that is applied.
