Patents by Inventor Igor Lumelskiy

Igor Lumelskiy 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).

  • Miniature power splitter
    Publication number: 20060033592
    Abstract: A power splitter that has a small package size and repeatable electrical characteristics. The power splitter includes a low temperature co-fired ceramic (LTTC) substrate with several layers. Electrical components such as resistors and capacitors are integrated within the LTTC substrate. A transformer is attached to the upper surface of the LTCC substrate and is electrically connected to the resistors and capacitors. The transformer provides impedance matching and dividing functions. The LTCC substrate has electrically conductive vias extending therethrough. The vias are used to connect the power splitter to an external printed circuit board. The vias are also used to make electrical connections between the layers of the LTCC substrate.
    Type: Application
