Procurement Notes

Verify the manufacturer designation, as sources list both Murata Manufacturing Co., Ltd. and RFMi for part number RF3702D. Confirm the package type and pin configuration against the official datasheet before integration. Ensure the supplier provides documentation matching the 426.44 MHz center frequency specification to avoid compatibility issues in the target circuit design.

Selection Notes

Select this component when a SAW filter with a 426.44 MHz center frequency is required. Consider the 1.0 MHz bandwidth and the specific insertion loss limits between 426.22 MHz and 426.66 MHz. Evaluate the physical package constraints and thermal requirements relative to the system's RF front-end architecture.
