Additional Details

SAW filters, such as the SAFEA1G90FA0F00R1S, operate based on the piezoelectric effect. When an electrical signal is applied to the piezoelectric material, it generates a mechanical wave that propagates along the surface of the crystal. This wave is then used to selectively filter signals based on their frequency. The performance characteristics of the filter are determined by the properties of the piezoelectric material and the design of the interdigital transducers (IDTs) on its surface.

For detailed technical specifications, including center frequency, bandwidth, and insertion loss, refer to the official datasheet provided by Murata Electronics North America. These specifications are critical for selecting the appropriate filter for specific application requirements.
