Patents by Inventor Matt Nishimoto

Matt Nishimoto has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Monolithically integrated switchable circuits with MEMS
    Patent number: 7382213
    Abstract: A reconfigurable circuit and a related method for its use, the circuit including multiple microelectromechanical systems (MEMS) switches connected between selected points in the circuit. The MEMS switches are controlled to select a desired circuit condition, such as an impedance matching condition, and then the switch conditions may be fused permanently. In the context of an impedance matching circuit, the MEMS switches may be used to optimize matching after circuit fabrication or after packaging, thereby allowing optimization even after potentially performance changing events.
    Type: Grant

    Date of Patent: June 3, 2008
    Assignee: Northrop Grumman Corporation
    Inventors: Jeffrey M. Yang, Matt Nishimoto, Gregory Rowan, Kelly Tornquist, Patty Chang-Chien
  • Asymmetric, optimized common-source bi-directional amplifier
    Patent number: 7239852
    Abstract: A common source, bi-directional microwave amplifier is described. More particularly, the present invention is a microwave, common source, bi-directional amplifier that includes a first amplification path and a second amplification path wherein the signal directional flow is controlled through the selective biasing of the first amplification path and the second amplification path. Each amplification path is designed to optimize desired performance. For signal flow through the first amplification path, the first amplification path is biased-on and the second path is biased-off. For signal flow through the second amplification path, the second amplification path is biased-on and the first path is biased-off.

  • Electronically programmable multimode circuit
    Patent number: 6944437
    Abstract: An electronically programmable multimode circuit is described. More particularly, the present invention is an electronically programmable multimode circuit that includes a first path and a second path wherein a mode and a signal directional flow direction is controlled through the selective biasing of the first path and the second path. A multimode circuit is produced that contains modes such as a phase shifter mode, an IQ modulation mode, an amplifier mode, a mixer mode, and a multiplier mode.
