1. balance input output piezoelectric filter is characterized in that comprising:

  • The piezoelectric substrate that comprises two first type surfaces;

    Be arranged on the grounding electrode in the described piezoelectric substrate;

    Be separately positioned at least one input electrode and at least one output electrode on two first type surfaces of described piezoelectric substrate,, described piezoelectric substrate arranged therebetween, thus, determined a balancing circuitry connection electrode so that relative with described grounding electrode;

    Wherein, piezoelectric substrate vibrates with the thickness extension vibration mode.
