SAW Filters are in stock at Tenco Electronics. SAW (surface acoustic wave) filters are electromechanical devices commonly used in radio frequency applications. Electrical signals are converted to a mechanical wave in a device constructed of a piezoelectric crystal or ceramic; this wave is delayed as it propagates across the device, before being converted back to an electrical signal by further electrodes.Tenco offers inventory, pricing, & datasheets for SAW Filters.
