    • A piezoelectric filter that includes a first substrate having at least one first piezoelectric resonator disposed on a main surface thereof; a second substrate having at least one second piezoelectric resonator disposed on a main surface thereof. A connection pattern extends around the first piezoelectric resonator and the second piezoelectric resonator and is disposed between the first substrate and the second substrate such that the main surface of the first substrate faces the main surface of the second substrate, and the first piezoelectric resonator is remote from the second piezoelectric resonator. A connecting layer bonds a pad disposed on the main surface of the first substrate to a pad disposed on the main surface of the second substrate, and is electrically connected to the first piezoelectric resonator and the second piezoelectric resonator.
    • 一种压电滤波器,包括:第一基板,具有设置在其主表面上的至少一个第一压电谐振器; 第二基板,其具有设置在其主表面上的至少一个第二压电谐振器。 连接图案围绕第一压电谐振器和第二压电谐振器延伸并且设置在第一基板和第二基板之间,使得第一基板的主表面面向第二基板的主表面,并且第一压电谐振器是远程的 从第二压电谐振器。 连接层将设置在第一基板的主表面上的焊盘与设置在第二基板的主表面上的焊盘接合,并且电连接到第一压电谐振器和第二压电谐振器。
