Modified hanma-hunsinger cell geometry for improved manufacturability of saw filters

Autor: Pierre Dufilie, Pascal Ventura, Frédéric Hecht

Publikováno v: 2016 IEEE International Ultrasonics Symposium (IUS).

High performance SAW filters typically incorporate cell structures with acoustic reflection for insertion loss reduction, triple transit suppression and size reduction. The electrical characteristics of the filters are sensitive to the reflection str
