PROBLEM TO BE SOLVED: To provide an amplifier capable of preventing breakdown of a transistor due to application of a high voltage thereto.SOLUTION: An amplifier has a signal processing unit (101) for separating an input signal into an amplitude component and a phase component, and outputting a plurality of bit signals depending on the amplitude component and phase component signals, and a plurality of amplification units (AMP1-AMPn) that input the phase component signals. Each of the plurality of amplification units includes first and second transistors (TA1, TB1) operating complementarily on the basis of the phase component signal, and a transformer (TR1) including primary and secondary inductors, where the primary inductor is connected between the drain and source of the second transistor. When the bit signal has a second value, the first transistor is turned off, and the second transistor is turned on.SELECTED DRAWING: Figure 1 |
