ABSTRACT:
A balanced filter suitable for a reduction of the filter size. The balanced filter comprises strip-line resonators (SL1a, SL1b) constituting resonance electrodes on the unbalanced side, strip-line resonators (SL2a, SL2b) disposed in adjacently opposed relation to the strip-lines on the unbalanced side and constituting resonance electrodes on the balanced side, strip-line resonators (SL3a, SL3b) disposed in adjacently opposed relation to the strip-lines on the balanced side and constituting stage constituting resonance electrodes, and impedance elements (Z) coupling the resonance electrodes on the balanced side to the stage constituting resonance electrodes.
