Abstract
An apparatus and a method are provided for, in an electronic device which generates a reference signal having a reference frequency, mixes the reference signal to an input signal for transmission, and amplifies power, outputting a control signal for turning off amplifying the power, if a frequency of a signal acquired at an arbitrary point after generating the reference signal or mixing the signals before amplifying the power is out of a designated frequency band, thus preventing burnout of a power amplifier.
