Abstract
An acoustic resonator filter package includes an acoustic resonator including a piezoelectric layer, a first electrode disposed on a first surface of the piezoelectric layer, and a second electrode disposed on a second surface of the piezoelectric layer; a first substrate having an upper surface on which the acoustic resonator is disposed, the first substrate comprising a first coupling member surrounding the acoustic resonator; a filter spaced apart from the acoustic resonator in an upward direction; a second substrate having a lower surface on which the filter is disposed, the second substrate including a second coupling member disposed above the first coupling member; and a connection member connecting the first coupling member and the second coupling member to each other, the connection member being made of a material different from a material of which the first coupling member and the second coupling member are made.
