    摘要: In one aspect of the invention, an acoustic device has a first coupled resonator filter (CRF) and a second CRF electrically coupled to one another in series. Each CRF has an input port, an output port, a bottom film bulk acoustic resonator (FBAR), an acoustic decoupler formed on the bottom FBAR, and a top FBAR formed on the acoustic decoupler. Each FBAR has a bottom electrode, a piezoelectric layer formed on the bottom electrode, and a top electrode formed on the piezoelectric layer. The decoupling layer capacitance arising between the two electrodes enclosing the acoustic decoupler in a CRF is configured to achieve targeted filter response. A compensating capacitance is introduced to improve the amplitude and phase imbalance performance of an unbalanced to balanced CRF by eliminating the existence of asymmetric port-to-ground or feedback capacitance at the balanced output port produced by the decoupling layer capacitance.
