Patents by Inventor Warren Brakensiek

Warren Brakensiek 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).

  • Patent number: 11784613
    Abstract: Packaged RF transistor amplifiers are provided that include a flat no-lead overmold package that includes a die pad, a plurality of terminal pads and an overmold encapsulation that at least partially covers the die pad and the terminal pads and an RF transistor amplifier die mounted on the die pad and at least partially covered by the overmold encapsulation. These packaged RF transistor amplifiers may have an output power density of at least 3.0 W/mm2.
    Type: Grant
    Filed: March 26, 2021
    Date of Patent: October 10, 2023
    Assignee: Wolfspeed, Inc.
    Inventors: Phil Saint-Erne, William Pribble, Warren Brakensiek, Bradley Millon
  • Patent number: 11715722
    Abstract: Fabrication of a bondwire inductor between connection pads of a semiconductor package using a wire bonding process is disclosed herein. To that end, the bondwire inductor is fabricated by extending a bondwire connecting two connection pads of the semiconductor package around a dielectric structure, e.g., a dielectric post or posts, disposed between the connection pads a defined amount. In so doing, the bondwire inductor adds inductance between the connection pads, where the added inductance is defined by factors which at least include the amount the bondwire extends around the dielectric structure. Such additional inductance may be particularly beneficial for certain semiconductor devices and/or circuits, e.g., monolithic microwave integrated circuits (MMICs) to control or supplement impedance matching, harmonic termination, matching biasing, etc.
