ABSTRACT:
A film bulk acoustic wave filter assembly includes a film bulk acoustic filter and an RF circuit. The film bulk acoustic filter unit cell includes a plurality of film bulk acoustic wave resonators. The number, area and arrangement of the resonators depend on the characteristics of the filter. In the film bulk acoustic wave filter, a metal layer made by CMOS processes is used as a lower electrode area of the film bulk acoustic wave filter or a suspended chamber. The film bulk acoustic filter can be integrated with the RF circuit using processes such as the CMOS process. It facilitates the integration of active devices, streamlining of system design and simplification of test processes, and has a great influence on the application of RF communication devices and integration of system-system-chip (SOC).
