Abstract: An microelectromechanical switch uses electrostatic attraction to draw a beam toward a contact and electromagnetic repulsion to disengage and repel the beam from the contact. The electrostatic attraction is generated by a gate electrode. The electromagnetic repulsion is generated between the beam and a magnetic coil positioned on the same side of the beam as the contact. The magnetic coil produces a magnetic field, which induces a current in the beam that repels the magnetic coil. The gate electrode and the magnetic coil may be co-planar or in different planes. A circuit may also operate a coil-shaped structure act as the gate electrode and the magnetic coil, depending on the configuration.

Abstract: A MEMS apparatus has a substrate, an input node, an output node, and a MEMS switch between the input node and the output node. The switch selectively connects the input node and the output node, which are electrically isolated when the switch is open. The apparatus also has an input doped region in the substrate and an output doped region in the substrate. The input doped region and output doped region are electrically isolated through the substrate—i.e., the resistance between them inhibits non-negligible current flows between the two doped regions. The input doped region forms an input capacitance with the input node, while the output doped region forms an output capacitance with the output node.

Abstract: A MEMS switch has a base formed from a substrate with a top surface and an insulator layer formed on at least a portion of the top surface. Bonding material secures a cap to the base to form an interior chamber. The cap effectively forms an exterior region of the base that is exterior to the interior chamber. The MEMS switch also has a movable member (in the interior chamber) having a member contact portion, an internal contact (also in the interior chamber), and an exterior contact at the exterior region of the base. The contact portion of the movable member is configured to alternatively contact the interior contact. A conductor at least partially within the insulator layer electrically connects the interior contact and the exterior contact. The conductor is spaced from and electrically isolated from the bonding material securing the cap to the base.

Abstract: Radio frequency (RF) isolators are described, coupling circuit domains operating at different voltages. The RF isolator may include a transmitter which emits a directional signal toward a receiver. Layers of materials having different dielectric constants may be arranged to confine the emission along a path to the receiver. The emitter may be an antenna having an aperture facing the receiver.
