Publication number: 20240087828Abstract: Microelectromechanical systems (MEMS) switches are disclosed. Parallel configurations of back-to-back MEMS switches are disclosed in some embodiments. An isolation connection of constant electrical potential may be made to a midpoint of the back-to-back switches. In some embodiments, a separate MEMS switch is provided as a shunt switch for the main MEMS switch. MEMS switch device configurations having multiple switchable signal paths each coupling a common input electrode to a respective output electrode are also disclosed. The MEMS switch device includes shunt switches each coupling a respective output electrode to a reference potential. The presence of a shunt switch coupled to an output electrode enhances the isolation of the signal path corresponding to that output electrode when the path is open.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: Analog Devices International Unlimited CompanyInventors: Padraig Fitzgerald, Philip James Brennan, Jiawen Bai, Michael James Twohig, Bernard Patrick Stenson, Raymond C.

Patent number: 9659717Abstract: 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.Type: GrantFiled: February 18, 2014Date of Patent: May 23, 2017Assignee: Analog Devices GlobalInventors: Check F. Lee, Raymond C. Goggin, Padraig L. Fitzgerald

Patent number: 9583294Abstract: 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.Type: GrantFiled: May 15, 2014Date of Patent: February 28, 2017Assignee: Analog Devices GlobalInventors: Check F.
