Communication equipment includes a circuit generating an RF input signal; a PA receiving a supply voltage, receiving the RF input signal, and providing an amplified version of the RF input signal as an output signal that is associated with an output power of the communication equipment; and an output circuit that includes an antenna for transmitting the output signal. The communication equipment also includes: a voltage detector circuit including sensing circuitry for sensing the supply voltage and a comparator for comparing the supply voltage to a first voltage threshold and generating a control signal when the supply voltage exceeds the first voltage threshold; and a disabling circuit coupled to the voltage detection circuit for disabling a portion of the communication equipment in response to the control signal to maintain output power of the communication equipment below a maximum output power level.
