Electroacoustic bandpass filter with flattened 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 f2f1. The frequencies f1 and f2 are chosen such that the insertion loss is smoothed.
