Guided elastic surface wave filter |
摘要 |
A resonator and resonator type wave filter formed by a piezoelectric body on which acoustic surface waves are guided and reflected and in which mode coupling in a direction transverse to the surface wave propagation is utilized. The transverse modes are controlled so as to provide improved response characteristics by minimizing suppressing and/or otherwise controlling unwanted modes of vibration in the body.
