Procurement Notes

Verify the specific suffix (e.g., -1 or -2) when ordering, as variants may differ in tolerance or packaging. Confirm the exact datasheet version with the manufacturer to ensure compliance with current specifications. Cross-reference part numbers carefully to avoid confusion between similar model series within the RFMi portfolio.

Selection Notes

Select this component for applications requiring a stable 916.5 MHz reference signal in space-constrained designs. Ensure the operating environment stays within the specified -40°C to 85°C range. Consider the 2.09 pF capacitance value for circuit matching requirements. Verify compatibility with surface-mount assembly processes.

Part Context

This part belongs to the RFMi SAW resonator family, which provides solutions for RF filtering and frequency control. These components are typically used in mobile devices and wireless infrastructure. The RO3144A specifically targets the sub-1 GHz frequency band, offering reliability for critical signal generation tasks in modern electronic systems.

Replacement Considerations

Check for direct substitutes like the RO3144A-1 or RO3144A-2 if available. Verify that any replacement matches the 916.5 MHz frequency and 2.09 pF capacitance exactly. Ensure the temperature range and package type are compatible with the existing design constraints before substitution.
