Additional Details

The B39700-B3897-Z510 SAW filter uses the piezoelectric effect to filter RF signals. The filter consists of interdigital transducers (IDTs) patterned on a piezoelectric substrate, such as lithium niobate (LiNbO3) or lithium tantalate (LiTaO3). These IDTs generate and detect surface acoustic waves, which are used to selectively pass or reject signals based on their frequency. The filter's performance is determined by the design of the IDTs and the properties of the piezoelectric material. Detailed specifications including center frequency, bandwidth, insertion loss, ripple, and attenuation can be found in the product datasheet.
