Abstract
A multi-band acoustic wave microwave filter, including a signal transmission path having an input and an output; a plurality of nodes disposed along the signal transmission path; a plurality of non-resonant branches respectively coupling one or more nodes to ground, wherein each non-resonant branch comprises at least one non-resonant element; and a plurality of resonant branches that couple one or more nodes to ground and include a plurality of resonators on said branches, wherein the plurality of resonators define a first band and at least one additional band and further wherein the difference between the lowest resonant frequency and the highest resonant frequency of the first band is at least 1.25 times the average separation of the resonators.
