Abstract: According to one mode of the inventive concept, an amplification device includes a first amplification unit configured to amplify an input signal when a power level of the input signal is within a first range, a second amplification unit configured to amplify the input signal when the power level of the input signal is within a second range, and an abnormality sensing unit configured to sense an occurrence of an abnormality in the second amplification unit. The abnormality sensing unit senses reverse power regarding an output of the second amplification unit to generate a sensed voltage and compares the sensed voltage with a reference voltage to sense whether an abnormality occurs in the second amplification unit.
