Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and pinout configurations before integration. Ensure compatibility with the target PCB footprint dimensions of 3.00mm x 3.00mm. Confirm that the 6-SMD no-lead package matches the assembly process requirements for the manufacturing line.

Selection Notes

Select this component when a SAW filter is required specifically for the L1 GPS band around 1.5675 GHz. Consider the 85 MHz bandwidth relative to the signal spectrum needs. Evaluate the 7 dB insertion loss against system sensitivity requirements. Compare physical dimensions against available board space constraints.
