Surface Acoustic Wave – AMT

What is so called “SAW (Surface Acoustic Wave)” travels as an acoustic wave on the surface of certain materials that show specific properties like elasticity. A device that uses this wave is easily found in many electrical gadgets such as mobile phones, radios, and even touch screens. By using SAWs in electronic components, SAW devices can be turned into several different functions like DC-to-DC converters, delay lines, filters, etc. Korea’s AMT (Advanced Microwave Technologies) gets to the bottom of what SAWs can do.

First built in 1998, AMT intends to develop and introduce Surface Acoustic Wave devices for the telecommunication stations. Since then, the firm has been providing a number of different SAW filters and the other electronic signal processing parts, and they are all going through AMT’s quality technology and manufacturing facilities. Main items include customizable high-performance bandpass SAW filter, resonators, delay lines, etc. They are applicable to digital wireless communication systems, wireless networks, internet, RF systems, satellite systems, etc.

AMT offers all types of IF SAW filters that ranges from 70MHz to 140MHz. For RF SAW filters, they are varied depending on which application: mobile phones, cordless phones, low power systems, and cellular BS phone systems. AMT produces four types such as One-Port, Two-Port, Front-End, and VCR RF-Modulator. The other SAW items are SAW delay lines and SAW devices for wireless LAN, wireless audio applications, and satellite receivers.
