  • Radio frequency subscriber drop units having printed circuit boards with ground plane layers and/or housings with ground walls
    Patent number: 10561030
    Abstract: Radio frequency subscriber drop units include a housing having an input port and an output port and a printed circuit board mounted in an interior of the housing. The printed circuit board includes a dielectric layer, a wiring layer that includes conductive wirings that comprise at least part of a communications path between the input port and the output port that is on a first face of the dielectric layer, and a ground plane layer that includes a conductive ground plane that is on a second face of the dielectric layer.
    Type: Grant
    Filed: September 28, 2017
    Date of Patent: February 11, 2020
    Assignee: CommScope, Inc. of North Carolina
    Inventors: Shi Man Li, Chi-Min Kang, Jui-Huang Chung
