Procurement Notes
Verify the complete part number including the trailing suffix to ensure correct packaging configuration. Confirm RoHS3 compliance status if required by specific environmental regulations. Cross-reference the manufacturer datasheet for pinout definitions and recommended soldering profiles to prevent thermal damage during assembly.
Selection Notes
Select this component when a 1.5824 GHz center frequency and 46.8 MHz bandwidth are required. Ensure the 5-SMD footprint fits the board layout constraints. Consider the 1.5 dB insertion loss impact on overall system sensitivity. Verify compatibility with existing RF matching networks before integration.
Part Context
This device is part of Raltron's RSF series of SAW filters, which targets mobile communication and navigation markets. The series offers various center frequencies tailored for specific global positioning standards. The RSF-1582.400-46800-1109-TR specifically addresses L1 band requirements common in consumer electronics.
Replacement Considerations
Check for direct substitutes within the RSF series that share identical electrical parameters. Verify mechanical footprint compatibility with the 5-SMD No Lead package. Ensure any replacement maintains the 1.5824 GHz center frequency specification.
