Abstract
One example includes an acoustic resonator filter bank system. The system includes a multiplex passive filter that is configured to provide a plurality of filtered versions of a radio frequency (RF) input signal. The system also includes a filter bank that comprises a plurality of filter blocks that are each configured to provide a plurality of pass-bands across a frequency spectrum. Each of the filter blocks includes an acoustic resonator. The system further includes a switch matrix that is configured to provide one of the filtered versions of the RF input signal to one of the filter blocks in the filter bank to provide an RF output signal having a frequency band corresponding to a respective one of the pass-bands.
