Patent Number: 6,806,774

Title: Power amplifier and communication device including power amplifier

Abstract: A resistor and a capacitor are provided for a variable impedance element which performs distortion compensation of a power amplifier. Thus, compensation of amplitude-amplitude distortion and amplitude-phase distortion can be separately adjusted. As a result, distortion of the power amplifier can be reduced effectively and a highly efficient operation is made possible.
