Abstract
A BAW resonator ladder topology pass-band filter can include a plurality of series branches each including BAW series resonators. A plurality of shunt branches can each include BAW shunt resonators, wherein the plurality of series branches are coupled to the plurality of shunt branches to provide the BAW resonator ladder topology pass-band filter. A high-impedance shunt branch can include a plurality of high-impedance BAW shunt resonators coupled together in-series to provide an impedance for the high-impedance shunt branch that is greater the other shunt branches in the BAW resonator ladder topology pass-band filter.
