Abstract: A bandpass filter includes input and output terminals, first and second acoustic resonators, and an acoustic coupling layer. The first acoustic resonator includes first and second electrodes, and a piezoelectric layer between the first and second electrodes. The first electrode of the first acoustic resonator is connected to the input terminal. The second acoustic resonator includes first and second electrodes, and a piezoelectric layer between the first and second electrodes. The acoustic coupling is provided between the second electrode of the first acoustic resonator and the first electrode of the second acoustic resonator. The output terminal is connected to the second electrode of the second acoustic resonator. A capacitor extends between the input terminal and the output terminal. The filter's frequency response includes at least two transmission zeros.
