ABSTRACT:
A radio signal transmitter for use in an automotive keyless entry system, is resistant to damage even when subject bending stresses. The radio code transmitter has a thin housing. A substrate for a transmitter circuit is housed within the thin internal space of the housing. A plurality of circuit components making up the transmitter circuit are mounted on the substrate. The circuit components are arranged in such a manner that relatively large components are near the edges of the substrate and relatively small components are nearer the center of the substrate.
