RO3075E

Resonators Overview

The RFMi RO3075E is a Surface Acoustic Wave (SAW) resonator designed for high-frequency applications. It operates at a nominal frequency of 345.1 MHz with a frequency tolerance of ±50 kHz and a static capacitance of 4.3 pF. The component utilizes a hermetically sealed ceramic package in the SM3030-6 form factor, measuring 3.00mm x 3.00mm. It supports surface mount termination styles and functions within an operating temperature range of -40°C to 105°C. The device offers frequency stability of 32ppb and complies with RoHS standards.

Resonators Feature Summary

• Hermetically sealed ceramic packaging ensures environmental protection and long-term reliability
• Quartz frequency stabilization provides precise signal generation for wireless systems
• Surface mount design facilitates automated assembly and compact circuit integration

Resonators Applications

• Wireless communication modules requiring stable reference frequencies
• RF front-end circuits in digital transmission equipment
• Oscillator designs needing high-frequency quartz stabilization

Resonators Procurement Notes

Verify the specific frequency tolerance variant required, as sources indicate both ±50kHz and ±100kHz specifications for similar part numbers. Confirm the exact package dimensions match the target PCB footprint. Ensure the supplier provides documentation confirming AEC-Q200 compliance if automotive qualification is necessary. Cross-reference the manufacturer designation to ensure authenticity from RFMi or Akoustis.

Resonators Selection Notes

Select this component when a 345 MHz SAW resonator is needed for compact wireless designs. Consider the SM3030-6 size constraint against available board space. Evaluate the thermal performance requirements against the -40°C to 105°C operational range. Compare the static capacitance value with the oscillator circuit design parameters to ensure proper impedance matching and frequency accuracy.
