Abstract: An electronic device for preventing or reducing damage to a radio frequency front end (RFFE). The electronic device including a memory device configured to store operating state information of a RFFE and a damage prevention condition of the RFFE, the RFFE providing a signal path for delivering a first transmission (TX) signal to an antenna, and a TX signal controller configured to generate a TX signal control signal in response to determining that the operating state information does not satisfy the damage prevention condition, the TX signal control signal causing the first TX signal to be blocked or a magnitude of the first TX signal to be reduced.
