ABSTRACT:
A bandpass filter network and method for bandpass filtering signals uses multiple acoustic resonators. The acoustic resonators may be Film Bulk Acoustic Resonators (FBARs) or Surface Acoustic Wave (SAW) resonators. The acoustic resonators are separated by one or more electrical components, for example, transistors of an amplifier, to provide isolation between the acoustic resonators.
