Electroacoustic bandpass filter having smoothed insertion loss

摘要

A bandpass filter operates with electroacoustically active components. The bandpass filter includes a first transducer segment having a spike in the insertion loss at a first frequency f₁ and a second transducer segment having a spike in the insertion loss at a second frequency f₂≠f₁. The frequencies f₁ and f₂ are chosen such that the insertion loss is smoothed.
