摘要： A high power slide tuning capacitor (200) integrated into a circuit board adapted to function at RF and microwave frequencies. The capacitor (200) includes a dielectric substrate (26) with a cavity (28) cut into a side of the substrate (26); a ground plane (24) mounted on a bottom surface of the dielectric substrate (26); a microstrip patch (22) mounted on a top surface of the dielectric substrate (26) and positioned above the cavity (28); and a movable dielectric stub (30) which engages the cavity (28) such that a variable length of the stub (30) is positioned beneath the microstrip patch (22). The microstrip patch (22) can be coupled to a desired circuit trace (20), effectively forming a shunt capacitor to ground.

摘要： A microelectronic tunable capacitor and a method for fabricating the capacitor are described. The capacitor is formed by a micro-actuator, a first fixed capacitor plate and a second swayable capacitor plate suspended over the first plate. The micro-actuator is formed by a pair of fixed electrodes positioned spaced-apart from each other sandwiching without contact a suspended arm electrode swayable between the pair of fixed eletrodes. The second swayable capacitor plate is mounted to the suspended arm and sways by an electrostatic force between the pair of fixed electrodes to suitably adjust a desirable capacitance for the tunable capacitor.
