Abstract
A bulk acoustic wave filter includes a substrate, a first electrode and a second electrode disposed on the substrate, a piezoelectric layer including a piezoelectric material, the piezoelectric layer disposed between the first and second electrodes, and a passive element disposed on one surface of a housing. The housing is coupled to the substrate to accommodate the piezoelectric layer, the first electrode and the second electrode.
