Abstract:
The invention relates to a device for protecting a near field communication router against possible over-voltages picked up by an antenna. The device includes two voltage-limiter elements between terminals of the antenna and a ground. A circuit detects the presence of an electromagnetic field in the vicinity of an operating frequency of the router, and controls the limiter elements, the limiter elements being active by default.
