description The utility model relates to the technical field of filters, and provides a bulk acoustic wave filter and a filter assembly. Comprising a first film bulk acoustic wave resonator, a second film bulk acoustic wave resonator, a third film bulk acoustic wave resonator, a fourth film bulk acoustic wave resonator, a fifth film bulk acoustic wave resonator, a sixth film bulk acoustic wave resonator and a seventh film bulk acoustic wave resonator which are connected in series between an input terminal and an output terminal. One end of each of a plurality of film bulk acoustic resonators connected in parallel is connected in parallel to a node between the first film bulk acoustic resonator and the second film bulk acoustic resonator, a node between the third film bulk acoustic resonator to the fifth film bulk acoustic resonator, and a node between the sixth film bulk acoustic resonator and the seventh film bulk acoustic resonator; and the other ends of the plurality of film bulk acoustic resonators connected in paral
