Abstract

A power amplifying device includes a first amplification circuit amplifying a first signal having a first frequency component and a second frequency component; a second amplification circuit amplifying a second signal received through an output node of the first amplification circuit; a filter circuit connected between a ground node of the first amplification circuit and a common ground to pass the first and second frequency components to the common ground through the ground node; and an inverting circuit that phase-inverts a signal including second harmonic components of the first and second frequency components that are received through the ground node of the first amplification circuit and provide the phase inverted signal to the output node of the first amplification circuit.
