Additional Details

The performance characteristics of the B39941-B4124-U410, such as center frequency, bandwidth, insertion loss, and rejection, are essential for selecting the appropriate SAW filter for a given application. SAW filters are typically fabricated using piezoelectric materials, like lithium tantalate (LiTaO3) or lithium niobate (LiNbO3), which exhibit excellent acoustic properties. The design of the interdigital transducers (IDTs) patterned on the piezoelectric substrate determines the filter's performance. These IDTs generate and detect surface acoustic waves, which are then used to filter the RF signal.
