About SAW Filters
SAW filters are electronic filters that are designed and manufactured using surface acoustic wave (SAW) technology. SAW technology uses piezoelectric transducers that, when excited, produce waves that are used to filter frequencies. Surface acoustic wave filters that operate in gigahertz (GHz) range are used widely in mobile communication systems. SAW filters are also used in radio frequency (RF) modems, alarm systems, wireless remote controls, satellite receivers, video transmission fields, telemetry systems, and mobile phone applications. SAW filter manufacturers differ in terms of capabilities and conform to a variety of regulatory requirements and quality standards.
