<p>A SAW resonator/filter structure (300) includes a transducer portion. The transducer portion includes a plurality of acoustically coupled sub-transducer portions (310 and 312) comprising conductive patterns having interdigitated open-ended fingers. The sub-transducer portions (310 and 312) are electrically coupled to each other in series in order to increase the port impedance of the SAW filter structure (300) while providing the widest bandwidth.</p> |
