A SAW resonator filter using longitudinal and transverse modes
A SAW resonator filter using not only transverse but also longitudinal modes is presented. The design principle permits to construct four-pole filters without cascading or parallel connection. The input and output transducers arranged side by side have equal construction characterized by unsymmetrical withdrawing weighting. Neighboring disturbing longitudinal modes are suppressed due to weighting determined by an iterative procedure. The successful application of the principle to a device is demonstrated by experimental measurements.
