Devices for use in highly integrated radio frequency transceivers utilize micro-electro-mechanical systems, or wobble motors, to form superior switches and to select and vary components that determine different frequencies of operation. Each device has a substrate with concentric rings of electrodes and contacts. A circular rotor is centrally pivoted or wobbled to engage the contacts along its circumferential edge. The rotor may be mechanically or materially modified to create symmetric or asymmetric forms which interact with one or more stationary capacitor electrodes on the substrate. The positioning of the rotor forms in terms of rotation, overlap and separation, relative to the capacitor electrodes, varies the capacitance.
