The SAW filter has a small size and is suitable for micro-sealing, good consistency, and no need to adjust.
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.
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.
In a mobile communication system, whether it is digital or analog, the circuit structure of its functional modules for transmitting and receiving signals is basically the same
Lithium niobate (LiNbO3 or LN) is among the most flexible and well-developed active optical substances. The crystal finds broad application in electro-optics, acousto-optics, nonlinear optics and guided-wave optics.
