Surface acoustic wave arrangement with a junction region between surface acoustic wave structures having a decreasing then increasing finger period
摘要:
In order to reduce scattering losses during the transmission of a surface acoustic wave signal, a surface acoustic wave arrangement has a junction between two mutually offset surface acoustic wave structures designed so that the finger period is reduced in the region of the junction, and varies continuously in the region of the junction.
