    摘要： The invention relates to a tractable filter comprising at least two resonating circuits (14a, 14b) arranged between two matching networks (4, 5), characterized in that: one resonator is connected, by a first of the ends thereof (14a
    1 , 14b
    1 ), to the ground M of the filter by plated through-holes (16), and by a second end (14a
    2 , 14b
    2 ) thereof to a MEMS network (12); the distance d between the two resonators forms an inductive inter-resonator coupling circuit (10); an inter-resonator coupling capacitor (11) is formed by two etched lines (11a, 11b) connected to the first and second resonators; the MEMS networks are distributed around the ends of the resonators; the MEMS networks are connected between the first and second resonators and the ground M by means of plated through-holes; and the filter includes a plurality of independent control voltages Vi (17) designed to operate the MEMS.

    摘要： A filter device is provided including a substrate (302) and a plurality of horizontal gap closing actuator (GCA) devices (550) disposed on a first surface of the substrate. The plurality of GCA devices includes and one or more GCA varactors (700). Each one of the plurality of horizontal GCA devices includes at least one drive comb structure (602a, 602b, 702a, 702b), at least one input/output (I/O) comb structure (616a, 676b, 716a, 716b), and at least one truss comb structure (604, 704) interdigitating the drive comb and the I/O comb structures. The truss comb structure is configured to move along a motion axis between at least a first interdigitated position and a second interdigitated position based on a bias voltage applied between the truss comb structure and the drive comb structure.

    摘要： A variable passive component (10) is provided for fabrication on a microelectromechanical system (MEMS) device. A conductive portion (16) is provided on a low-profile sliding dielectric sheet (18) that cooperates with a conductive portion (14) disposed on a substrate (12) 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.
