Abstract
A safe area voltage and current interface is provided that includes an antenna and mode selection unit, an antenna tuner unit and an interface unit. The antenna and mode selection unit determines a frequency mode and an antenna mode for an output signal. The antenna tuner unit is directly connected to the antenna and mode selection unit and is configured to tune the output signal based on the frequency mode and the antenna mode determined by the antenna and mode selection unit. The interface unit is directly connected to the antenna tuner unit and is configured to ensure that a current and voltage level of the output signal does not exceed an intrinsically safe current and voltage level, while maintaining the peak current level of the output signal to a level sufficient to drive an electronic component disposed in an unsafe environment.
