Additional Details

While specific technical data, such as center frequency, bandwidth, and attenuation levels, can be found on the Murata datasheet for SAFFB1G58FA0F0AR14, SAW filters typically use piezoelectric materials to create and detect acoustic waves on the device surface. The filter's specific performance characteristics are largely determined by the design of the interdigital transducers (IDTs). These filters are typically intended for use in a 50-ohm impedance environment; thus, proper impedance matching is critical.

The PCB layout should be carefully designed to minimize parasitic inductance and capacitance, which can negatively impact filter performance. Adhering to Murata's recommended soldering profile during the assembly process is crucial to ensure reliable connections and prevent damage to the component. SAW filters are susceptible to electrostatic discharge (ESD), necessitating proper handling precautions.
