Abstract
In an apparatus having an insulative substrate, a power circuit is mounted on one surface of the substrate and connected to receive power from a mains supply for rectifying the AC energy of the supply and supplying the rectified energy to a pair of power lines. A high frequency source is mounted on the same surface as the power circuit and electrically connected to the power lines for converting the rectified energy into oscillation energy. A shield casing, which is electrically connected to one of the power lines which is lower in impedance than the other, encases the high frequency source. A conductor, printed on the other surface of the substrate, is substantially aligned with a portion of the shield casing which is positioned between the power circuit and the high frequency source, the conductor being electrically connected to the power line having the lower impedance to suppress radiation which would otherwise leak through a gap between the shield casing and the substrate.
