Abstract
An integrated tunable resonator for radio includes an RF resonator having a micromechanical tunable capacitor with high Q- (quality factor) value. A first conducting layer ( ) forms the first capacitor electrode ( ), and/or the electrodes ( ) to create the electrostatic force on a movable micromechanical structure ( ), and the interconnecting wire ( ) between the inductor coil ( ) and the capacitor electrode. This arrangement with the use of a dielectric insulating layer provides a substantial improvement to the linearity, power consumption, occupation space and reliability of RF resonator circuits.
