摘要
In an acoustic surface wave multimode filter comprising a pair of acoustic surface wave resonators and a bus bar on a piezoelectric substrate with the bus bar shared by the resonators, the bus bar is rendered thicker than the resonators. Preferably, the bus bar should be about twice as thick as the resonators.
