Additional Details

Specific technical specifications, such as the center frequency, bandwidth, insertion loss, and rejection characteristics, are crucial for selecting the appropriate SAW filter for a given application. The B39861-B4161-U410 is typically fabricated using piezoelectric materials, such as lithium tantalate (LiTaO3) or lithium niobate (LiNbO3), which exhibit excellent acoustic properties. The filter's performance is determined by the design of the interdigital transducers (IDTs) patterned on the piezoelectric substrate. These IDTs generate and detect surface acoustic waves, which are then used to filter the RF signal. Consult the datasheet for detailed electrical characteristics.
