Modem having an electromagnetic shield for a controller

摘要

An electromagnetic shield providing for input/output signal paths includes: a carrier 101 having a shielding surface 103 that has electromagnetic shielding properties; a plurality of signal paths 107 mechanically coupled to the carrier 101; a plurality of filtering elements 109 corresponding to the plurality of signal paths 107 and electrically coupled, respectively, from the plurality of signal paths 107 to the shielding surface 103; and an enclosure 101 constructed from a material having electromagnetic shielding properties and having a perimeter edge 113 that is arranged and constructed to electrically couple the enclosure 111 to the shielding surface 103 at an interface so as to sandwich the plurality of filtering elements 109 between the perimeter edge 113 and the shielding surface 103 at the interface such that the plurality of signal paths 107 pass through the interface.
