  • Patent number: 9531167
    Abstract: The present disclosure presents a device and method for connecting an RF generator to a coaxial conductor. The device includes a substrate, a radio frequency generator on the substrate, and a coaxial conductor coupled to a first surface of the substrate. The coaxial conductor includes a conductive core and a conductive shield around the conductive core and is configured to transmit the radio frequency signal to a radiation device. The device includes a cap coupled to the substrate and extending from a second surface of the substrate opposite the first surface. The cap includes an outer wall and a center post. The outer wall is electrically connected to the conductive shield of the coaxial conductor and the center post is electrically connected to the conductive core of the coaxial conductor. An output pad of the radio frequency generator is electrically connected to the conductive core.

  • Patent number: 9349693
    Abstract: A system and method for packaging a semiconductor device that includes a structure to reduce electromagnetic coupling are presented. The semiconductor device is formed on a substrate. A cover is affixed to the substrate so as to extend over the semiconductor device. An isolation structure of electrically conductive material is coupled to the cover in between components of the semiconductor device, with the isolation structure being configured to reduce inductive coupling between those components during an operation of the semiconductor device. In one version, the isolation structure includes a first leg extending from a ground connection along a side wall of the cover to a cross member contiguous with a primary cover wall that extends over the semiconductor device between the components to be isolated electromagnetically.
