Additional Details

The SAFEB1G57KE0F0014 SAW filter uses the piezoelectric effect to create a mechanical wave, which interacts with the RF signal. The filter's characteristics are defined by the physical properties of the piezoelectric material and the design of the interdigital transducers (IDTs) on the surface. The '14' at the end of the part number likely refers to specific packaging or production lot details.

Murata's SAW filters are known for their high quality and reliability, making them suitable for demanding applications in various wireless communication standards. Careful consideration is given to insertion loss, group delay ripple, and stopband attenuation during the design phase to ensure optimal performance in the target application.
