Claim 0:
1. An apparatus, comprising:
a filter comprising a plurality of cascaded resonator stages;
a first set of one or more cascaded resonator stages coupled between an input to the filter and a first output of the filter, each cascaded resonator stage of the first set comprising a first series micro-acoustic resonator and a first parallel micro-acoustic resonator; and
a second set of one or more cascaded resonator stages coupled between the first output of the filter and a second output of the filter, each cascaded resonator stage of the second set comprising a second series micro-acoustic resonator and a second parallel micro-acoustic resonator, wherein the filter is configured to:
apply a first bandpass filter frequency response to a first signal propagating from the input to the filter to the first output of the filter via the first set of one or more cascaded resonator stages; and
apply a second bandpass filter frequency response to a second signal propagating from the input to the filter to the second output of the filter via the first and second sets of cascaded resonator stages.
