description PURPOSE: A linearizer for canceling resonance and a high power amplifying system and a high power amplifying method using the same are provided to greatly reduce power consumption by performing a controlling operation through a minimum voltage and a current. CONSTITUTION: A high power amplifying system(1) includes a band pass filter(10), a high power amplifier(20), and a resonance cancellation linearizer(30). The bandpass filter is placed in the front end of the resonance cancellation linearizer and the high power amplifier. The band pass filter passes through only a signal with the frequency of a pass band among input signals which are inputted into the high power amplifier. The high power amplifier amplifies an input RF(Radio Frequency) signal so that the input RF signal has an output level which is fit for a communications environment. The resonance cancellation linearizer eliminates nonlinear distortion due to a noise component in the RF signal which is amplified with the high power amplifier.
