Lithium niobate surface acoustic wave chip is a kind of chip made by using the surface acoustic wave technology of lithium niobate crystal. Such chips are commonly used in areas such as wireless communications, sensing and filters. Surface acoustic wave technology uses sound wave propagation in crystal to realize signal processing function.
Lithium niobate is a kind of crystal material with good piezoelectric and surface wave properties, so it is widely used in the manufacture of surface acoustic wave devices. By depositing electrodes on the lithium niobate crystal and applying an electric field, the surface acoustic waves in the crystal can be excited to achieve signal transmission and processing.
Lithium niobate surface acoustic wave chips are often used as filters in wireless communications to help filter out unwanted frequency components, thereby improving the performance of communication systems. They can also be used in sensors to detect changes in environmental parameters, such as pressure, temperature and humidity, by measuring the characteristics of surface acoustic waves.
