Abstract
An impedance matching wave filter includes an original wave filter and a match circuit. The match circuit is connected in parallel with the original wave filter and is able to be varied to produce impedance matching with the original wave filter in order to improve the condition of the return loss and to lower signal fading and signal distortion.
