RO3023A-1

Resonators Overview

The RO3023A-1 is a one-port surface acoustic wave (SAW) resonator manufactured by RFMi. It operates at a nominal frequency of 433.97 MHz with a frequency stability of 32 ppb. The component utilizes SMD/SMT termination and is housed in a compact SM5035-4 package measuring 5 mm in length, 3.5 mm in width, and 1.6 mm in height. It supports an operating supply voltage of up to 30 VDC and functions within a temperature range of -40°C to +85°C. The load capacitance is specified at 2.4 pF, ensuring precise signal generation for radio frequency applications.

Resonators Procurement Notes

Verify the specific datasheet version for the RO3023A-1 to confirm RoHS compliance status, as public records indicate varying information regarding lead-free certification. Ensure that the ordering suffix matches the required packaging configuration, such as reel quantities, before finalizing procurement orders to avoid compatibility issues during assembly.

Resonators Selection Notes

Select this component when a single-port SAW resonator is required for 433 MHz ISM band applications. Consider the 32 ppb stability requirement against system tolerance needs. Evaluate the 5x3.5x1.6 mm footprint against available board space. Confirm that the 2.4 pF load capacitance aligns with the oscillator circuit design specifications.

Resonators Part Context

The RO3023A-1 belongs to the RFMi RO series of SAW resonators. These components are designed for digital and wireless communication devices. RFMi, now part of Akoustis, specializes in frequency control solutions using SAW, crystal, and ceramic technologies. This model represents a standard surface-mount option for fixed-frequency generation.

Resonators Replacement Considerations

Public data does not list confirmed direct substitute part numbers for the RO3023A-1. Engineers must evaluate alternative SAW resonators based on matching frequency, package dimensions, and stability parameters rather than relying on official cross-reference lists.
