Electroacoustic bandpass filter with flattened insertion loss.

摘要

A bandpass filter BFP with flattened insertion loss is presented. This bandpass filter is operated by an electroacoustic active device. The bandpass filter includes a first converter segment having an insertion loss peak at a first frequency f1, and a second converter segment having an insertion loss peak at a second frequency f2 different from f1. These frequencies f1 and f2 are set so that the insertion loss is flattened. [Selection] Figure 1
