RO3144D

Overview

The RO3144D is a surface-mount SAW resonator manufactured by RFMi, designed for high-frequency signal processing applications. It operates at a center frequency of 916.5 MHz with a frequency stability of 32 ppb. The component utilizes a compact ceramic package, specifically the SM3838-8 form factor measuring 3.8 mm x 3.8 mm, ensuring hermetic sealing and quartz frequency stabilization. It is qualified under AEC-Q200 standards, supporting automotive-grade reliability requirements. The device features a load capacitance of 2.1 pF and is intended for board mount installation in wireless communication systems.

Feature Summary

• Hermetically sealed ceramic package providing robust environmental protection
• Quartz-based frequency stabilization for precise timing control
• Automotive-grade qualification ensuring reliability in harsh conditions
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Wireless communication modules requiring stable reference frequencies
• Automotive infotainment and telematics systems
• IoT devices utilizing sub-GHz ISM bands
• RF front-end circuits in mobile handsets

Procurement Notes

Verify that the specific suffix variant (e.g., -1 or -2) matches the required load capacitance and tolerance specifications for the target circuit design. Confirm AEC-Q200 compliance if automotive deployment is intended. Ensure the supplier provides official datasheets to validate the 32 ppb stability and 916.5 MHz center frequency against system requirements before finalizing orders.

Selection Notes

Select this component when a stable, low-profile resonator is needed for 916.5 MHz applications. Consider the 2.1 pF load capacitance for impedance matching. The AEC-Q200 qualification makes it suitable for automotive use cases where long-term reliability and temperature stability are critical. Compare physical dimensions against available PCB real estate to ensure compatibility with the SM3838-8 footprint.

Part Context

The RO3144D belongs to RFMi's SAW resonator portfolio, which leverages Surface Acoustic Wave technology for timing and filtering solutions. As an Akoustis brand product, it integrates advanced ceramic packaging techniques. This series supports emerging wireless standards and IoT connectivity needs, offering a balance between performance, size, and cost-effectiveness for mass-produced electronic devices.

Replacement Considerations

Direct substitutes include the RO3144D-1 and RO3144D-2 variants from the same manufacturer family. These alternatives share the 916.5 MHz operating frequency but may differ in load capacitance or tolerance specifications. Verify electrical parameters and pinout compatibility before swapping components to ensure circuit functionality remains intact.
