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.
Claims20
A passive radio frequency (“RF”) subscriber drop unit, comprising:
- a housing having a top wall and a plurality of sidewalls that define an open interior;
- a female coaxial input port that extends from outside of the housing to the open interior of the housing;
- a female coaxial output port that extends from outside of the housing to the open interior of the housing;
- a printed circuit board mounted in the open interior of the housing;
- and
- a ground wall that projects downwardly from an interior face of the top wall, the ground wall extending between the sidewalls, wherein the ground wall is electrically connected to a conductive ground plane of the printed circuit board.
A passive radio frequency (“RF”) subscriber drop unit, comprising:
- a housing having a top wall and a plurality of sidewalls that define an open interior;
- a female coaxial input port that extends from outside of the housing to the open interior of the housing;
- a female coaxial output port that extends from outside of the housing to the open interior of the housing;
- and
- a printed circuit board mounted on a plurality of posts that extend downwardly from an interior face of the top wall of the housing into the open interior of the housing, wherein at least one of the plurality of posts is electrically connected to a conductive ground plane of the printed circuit board.
