  • Techniques for routing electrical signals through electrical components and related methods
    Patent number: 10986730
    Abstract: Substrates configured to route electrical signals may include a first dielectric material and an electrically conductive material located on a first side of the first dielectric material. A second dielectric material may be located on a second, opposite side of the first dielectric material. A series of voids may be defined by the second dielectric material extending from the first dielectric material at least partially through the second dielectric material. Footprints of at least some of the voids of the series of voids may at least partially laterally overlap with the electrically conductive material.
    Type: Grant
    Filed: May 21, 2019
    Date of Patent: April 20, 2021
    Assignee: Microsemi Semiconductor ULC

  • Multi-width waveguide including first and second waveguide regions of differing widths and heights for providing impedance matching to an integrated circuit
    Patent number: 10622695
    Abstract: A waveguide. The waveguide may include a first waveguide region that includes a signal trace with a first width. The waveguide may further include a second waveguide region that includes the signal trace with a second width. The first width may be different from the second width. The signal trace may be configured to transmit an electrical signal. The signal trace with the second width may be configured to couple with an integrated circuit.
