Abstract
A variable passive component is provided for fabrication on a microelectromechanical system (MEMS) device. A conductive portion is provided on a low-profile sliding dielectric sheet that cooperates with a conductive portion disposed on a substrate to provide a variable passive component. The passive component can be a variable inductor provided by moving a shorted spiral inductor formed on the dielectric sheet over a spiral inductor on the substrate with varying degrees of overlap causing varying inductance values. The passive component can be a variable capacitor that consists of a large conductive pad on a dielectric plate which slides over two adjacent pads on the substrate with varying overlap causing varying capacitance values.
