ABSTRACT:
A linear amplifier for amplifying a composite signal of plural frequency components to improve high efficiency without lowering the efficiency of a power load, includes a nonlinear amplifier circuit to which a signal having plural different frequency components is inputted, a 2nd-order distortion arithmetic circuit for generating and outputting a 2nd-order distortion component of the signal having the plural different frequency components, and an injection unit for injecting the 2nd-order distortion component to the signal having plural different frequency components. The nonlinear amplifier amplifies the signal injected with the 2nd-order distortion component.
