Additional Details

The TA1458A SAW filter operates based on the piezoelectric effect, converting electrical signals into mechanical waves and back again. The filter's frequency response is precisely determined by the physical properties of the piezoelectric substrate and the design of the interdigital transducers (IDTs). It is commonly used in the intermediate frequency (IF) stage of radio receivers and transmitters. The filter's specific frequency and bandwidth are tailored to the application it is designed for. It typically operates within a specific temperature range, ensuring stable performance under varying environmental conditions. The device is RoHS compliant, adhering to environmental standards for hazardous substance restrictions. The compact SMD package is designed for automated assembly processes, reducing manufacturing costs and improving production efficiency. This specific filter is engineered to meet the demands of modern wireless communication, delivering optimal signal integrity and performance.
