What is a ตัวกรองเลื่อย?

A Surface Acoustic Wave (SAW) filter is an electronic filter that uses surface acoustic waves to select or limit frequencies of high-frequency signals. These filters are widely used in wireless communication, GPS, mobile phones, and Wi-Fi devices. SAW filters consist of a substrate made of piezoelectric materials (such as quartz or lithium niobate) with electrodes placed on its surface. When an electrical signal is applied, the piezoelectric effect generates surface acoustic waves that pass through the material. The filter allows specific frequencies to pass while blocking others. SAW filters operate at very high frequencies, offering wide-band, high-performance filtering, making them essential in communication and satellite systems. Their compact size and low power consumption are notable advantages.

Application of ตัวกรองเลื่อย

✅Mobile Phones
In mobile phones, SAW filters are used to improve call quality and data transmission. By selectively allowing different frequency bands, they filter out noise, improving call clarity and communication speed.
✅GPS Devices
SAW filters are used in GPS devices to precisely select signals. Since GPS signals are weak, SAW filters remove unwanted frequencies to ensure accurate location data.
✅Wi-Fi Routers
SAW filters in Wi-Fi routers help maintain stable wireless signals. They prevent signal interference, particularly in high-frequency bands, ensuring consistent and high-quality internet connectivity.
