Interface apparatus, connector apparatus and method of reducing electromagnetic interference

摘要

A subassembly apparatus includes a substantially shieldable interior chamber for housing at least one source of electromagnetic radiation, a connector plane external to the interior chamber for locating an end surface of a connector, and a launch window for locating an end surface of a waveguide, where the launch window is in or adjacent the connector plane. The apparatus also includes an internal propagation path extending from the interior chamber to the launch plane including a barrier of electrically conductive material disposed in the propagation path, the barrier being arranged to shield a planar region from electromagnetic radiation emitted from within the interior chamber, the planar region including substantially the connector plane substantially excluding the launch window.
