According to the present invention, disclosed is a microwave variable filter using dual mode. According to the present invention, the filter comprises a cylindrical cavity realizing a resonance mode having a plurality of resonant frequencies that are different from each other, and a plurality of slot irises formed in the cavity. A difference between the plurality of resonant frequencies that are different from each other can be determined according to a relative position of the plurality of slot irises. Also, since the relative position of the plurality of slot irises is properly adjusted, a transfer zero point is added by actively using an offset interaction with other modes around a used mode and thereby a blocking bandwidth can be widened. Moreover, in order to realize rapid roll-off of a transfer coefficient, a cavity is added and connected to the cylindrical cavity with the slot iris. Since the dimension of the cylindrical cavity the additional cavity of such filter is mechanically ...
