Latest Patents

Steffen Link holds a patent for "Surface acoustic wave devices using piezoelectric film on silicon carbide." This invention features an acoustic resonator that includes a piezoelectric thin film (PTF) on a carrier substrate. The PTF confines a fundamental shear-horizontal (SH0) surface-acoustic wave (SAW) within the film. The design incorporates an input bus line connected to an input source and a ground bus line linked to a ground potential. Additionally, the resonator includes first and second grating reflectors at either end of the PTF, along with interdigital transducers (IDTs) positioned between the reflectors. Each IDT consists of an input electrode connected to the input bus line and a ground electrode linked to the ground bus line. This innovative approach enhances the functionality and efficiency of acoustic devices.
