SAW and BAW Sensitive Elements and Blanks
SAW (Surface Acoustic Wave) and BAW (Bulk Acoustic Wave) sensitive elements and blanks are used in various applications such as filters, oscillators, and resonators. These devices are commonly used in wireless communication systems, such as cellphones, where they play a crucial role in enabling frequency filtering and signal processing.
SAW devices use a piezoelectric substrate such as quartz to convert electrical signals into acoustic waves, which propagate on the surface of the substrate. The acoustic waves can be used to filter or delay electrical signals. BAW devices use a piezoelectric material such as aluminum nitride to convert electrical signals into acoustic waves that propagate inside the substrate.
Sensitive elements are the active components of the devices, while blanks are the unprocessed substrates that are used to create the sensitive elements. Both SAW and BAW devices can be manufactured using a variety of substrates and materials to achieve different performance characteristics.
