RO3156A-2

Overview

The RO3156A-2 is a surface-mount SAW resonator manufactured by Akoustis- RFMi, designed for fundamental-mode frequency stabilization in fixed-frequency transmitters. It operates at a center frequency of 868.95 MHz with a capacitance of 2.1 pF and a tolerance of 32 ppb. The component supports an operating temperature range from -40°C to 85°C and utilizes a compact surface-mount package with a maximum height of 0.054 inches (1.38 mm).

Feature Summary

• Provides reliable fundamental-mode quartz frequency stabilization for fixed-frequency transmitters.
• Features a hermetically sealed ceramic package for environmental protection.
• Complies with AEC-Q200 automotive qualification standards.

Applications

• Fixed-frequency transmitter applications requiring stable oscillation.
• ISM band devices operating around 868.95 MHz.
• Automotive electronics systems meeting AEC-Q200 requirements.

Procurement Notes

Verify the specific suffix designation when ordering, as it may indicate variations in packaging or testing criteria distinct from the base part number. Confirm that the required operating temperature range aligns with the specified -40°C to 85°C limits. Ensure compatibility with surface-mount assembly processes given the small form factor. Cross-reference the manufacturer's latest documentation to confirm current availability and any updates to the RoHS compliance status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring precise frequency control at 868.95 MHz with minimal size constraints. The 2.1 pF load capacitance must be matched with external circuit components to achieve the target oscillation frequency. Consider the thermal performance within the -40°C to 85°C range during system integration. This resonator is suitable for applications demanding high reliability and automotive-grade certification without sacrificing footprint efficiency.

Part Context

The RO3156A-2 belongs to the family of SAW resonators produced by Akoustis- RFMi, formerly RF Monolithics. These components are engineered for robust performance in wireless communication modules. The product line emphasizes compactness and stability, utilizing advanced ceramic packaging techniques. It serves as a critical frequency-determining element in various RF front-end architectures.

Replacement Considerations

The RO3156A is listed as a related part number. Verify if the non-suffix variant meets the specific packaging or testing requirements needed for the application. Direct substitution requires confirmation of identical electrical parameters and mechanical dimensions.
