As one of the main ways and means of obtaining information in the natural and productive fields, force transducer plays a key role in modern industrial production, especially in automated production processes.
Quartz crystals are an important electronic material. Quartz wafers cut in a certain direction will generate an electric field or electric charge proportional to the stress when subjected to mechanical stress.
The basic structure of the SAW filter is to fabricate two acoustic and electrical transducers on the polished surface of the substrate material with piezoelectric properties - the interdigital transducer.
Lithium niobate crystal is an important multifunctional crystal with good nonlinear optical properties, large nonlinear optical coefficient, and non-critical phase matching.
The effective filtering frequency range of common interference filters is from several KHz to MHz, and the effective filtering frequency of RF interference filters is from several KHz to more than GHz.
Wafer refers to a silicon wafer used for silicon semiconductor integrated circuit fabrication. Because of its circular shape, it is called a wafer.
