Abstract
A frame construction for a radio telephone or the operating device of a radio telephone. The radio telephone comprises a frame on which printed circuit boards containing telephone electronics are secured on both sides of a substantially flat, electrically conductive frame plate. The frame plate together with ground foils of the printed circuit boards form EMI-shielding for the components located on the sides of the printed circuit boards which face the frame plate. The frame plate preferably has a raised edge to which a printed circuit board is secured. Radio telephone housing parts are located on the two sides of the frame plate to form the radio telephone housing.
