Resonators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as RO3104A-1 indicate distinct electrical or mechanical specifications compared to the base model. Confirm RoHS compliance status and packaging format, typically tape and reel, against current manufacturer documentation. Ensure the selected part matches the required frequency tolerance and temperature range for the target application environment before finalizing procurement.

Resonators Selection Notes

Select this component based on its specific 303.825 MHz center frequency and ±50 kHz tolerance requirements. Evaluate the need for 30 VDC operating voltage capability and the -40°C to +85°C temperature range. Consider the surface mount form factor and physical dimensions for PCB layout constraints. Ensure compatibility with SAW resonator circuit designs rather than quartz crystal oscillators.

Resonators Part Context

The RO3104A-1 belongs to the RFMi family of SAW resonators, which are engineered for industrial, commercial, and consumer applications. RFMi, now part of Akoustis, specializes in RF components using SAW, Xtal, and ceramic technologies. This series provides single-port and dual-port options designed to integrate directly into transmitter stages, offering reliable frequency stability without the complexity of active oscillator circuits.

Resonators Replacement Considerations

Direct substitutes must match the 303.825 MHz frequency, SAW type, and similar electrical parameters. Verify pinout compatibility and package dimensions for direct replacement. Cross-reference with other manufacturers' SAW resonators offering equivalent tolerance and temperature ratings.
