Patents by Inventor Dai NINOMIYA

Dai NINOMIYA 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).

  • High-frequency amplifier
    Patent number: 11283415
    Abstract: A MIM capacitor is included in any one or more of a first matching circuit and a second matching circuit. The mat capacitor performs impedance matching of a fundamental wave included in a high-frequency signal with a transmission line, and forms a short-circuit point for a harmonic included in the high-frequency signal at a connection point with the transmission line.
    Type: Grant
    Filed: July 14, 2017
    Date of Patent: March 22, 2022
    Assignee: Mitsubishi Electric Corporation
    Inventors: Dai Ninomiya, Eigo Kuwata, Kazuhiko Nakahara, Makoto Kimura, Yoshitaka Kamo

  • Impedance tuner and signal amplification device
    Patent number: 11005452
    Abstract: A control circuit (16) is configured to detect the impedance P1 of a load (3) and control each of the reactance value L1 of a first variable reactance element (12), the reactance value L2 of a second variable reactance element (14), and the phase shift amount ? of a phase shifter (15) on the basis of the detected impedance P1. Consequently, impedance matching can be achieved even with the phase shifter (15) that performs discrete phase shift control.
