<p>A device and a method for impedance matching are disclosed. According to reflected signal intensity SN and power Pn of a radio power amplifier, the control voltage of equivalent impedance is adjusted through a corresponding judging condition, thereby adaptive matching is realized between the radio power amplifier and a matching object. Utilizing the device and the method, designing of an adaptive matching circuit is simplified, the period of handset designing and debugging is shortened, the practical applicability of the adaptive matching circuit is improved, and the quality of handset calling is enhanced, and the stability and linearity of the radio power amplifier and the radio performance index of the complete handset are improved completely.</p> |
