What Are SAW Resonators?

Surface-acoustic-wave resonator. The main function principle of SAW surface acoustic wave elements is to use the piezoelectric properties of piezoelectric materials and use input and output transducers to convert the input signals of radio waves into mechanical energy. After processing, the mechanical energy is converted into electrical signals. In order to achieve the goal of filtering unnecessary signals and noise, and improving the quality of receiving. It is widely used in various wireless communication systems, televisions, video recorders and GPS receivers.

Surface acoustic wave (SAW) resonator

The main function is to filter out noise, which is simpler and smaller in size than traditional LC filters. The production of SAW surface acoustic wave components can be divided into wafer cleaning, metallization, photoresist, development, etching, photoresist removal, cutting, packaging, and other related steps.It has mass production, low loss, and high selectivity. Suitable for all types of mobile phones. With stable performance and small size, it is mainly used in wireless devices. The FL series of SAW filters is mainly used in cellular applications such as mobile communications and receivers. The FM series has low loss, high strength exclusivity, and low matching to external impedance.

It can be applied to automotive TPMS, remote keyless entry (RKE), security systems and active RFID tags.
