Abstract
An impedance matching system, a network analyzer having the same, and an impedance matching method thereof are disclosed. The system includes a signal extractor to extract an output signal and an input signal having at least a portion of an electric current outputted through a load and at least a portion of an electric current inputted through the load, respectively, a processor to process the output signal and the input signal extracted from the signal extractor, a comparator to compare a phase and an amplitude of the output signal with a phase and an amplitude of the input signal, respectively, a coefficient calculator to calculate a reflection coefficient using the comparative result provided from the comparator, and a circuit controller to generate a signal for controlling a matching circuit, which matches the phase and the amplitude of the output signal with the phase and the amplitude of the input signal, respectively, so as to ensure the reflection coefficient to have a predetermined value.
