Abstract

A component is designed to work with acoustic waves. Embodiments have an improved temperature gradient of the frequency range and have increased performance strength. To this end, the component includes a stack of layers having a lower bonding layer, an electrode layer, an upper bonding layer, a compensation layer, and a trimming layer.
