RO3073A

Resonators Overview

The RO3073A is a surface acoustic wave (SAW) resonator manufactured by RFMi, designed for low-power wireless communication applications. It operates at a nominal frequency of 315.00 MHz with a load capacitance of 4.1 pF and a frequency stability of 10 PPM. The component utilizes an SM5035-4 surface-mount package, measuring 5 mm in length, 3.5 mm in width, and 1.53 mm in height. It supports a maximum operating voltage of 30 VDC and functions within a temperature range of -40°C to +85°C.

Resonators Feature Summary

Resonators Procurement Notes

Verify the specific suffix designation when ordering, as variants such as RO3073A-16 or RO3073A-1 may exhibit slight frequency deviations despite sharing the base model number. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure electrostatic discharge precautions are observed during handling due to the sensitive nature of SAW devices.

Resonators Selection Notes

Select this component for designs requiring stable oscillation at 315 MHz with minimal power consumption. The 4.1 pF load capacitance requirement must be matched by the circuit design to ensure accurate frequency performance. Consider the SM5035-4 footprint constraints during PCB layout to accommodate the specified physical dimensions.

Resonators Part Context

The RO3073A belongs to RFMi's broader portfolio of timing and frequency products, which includes SAW resonators, filters, and various oscillator types. This series targets emerging wireless markets where size and power efficiency are critical. The component serves as a fundamental frequency reference in RF front-end circuits.

Resonators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Variants within the same family, such as RO3073A-1 or RO3073A-4, share similar specifications but may differ in precise frequency tolerances or packaging details. Cross-referencing with official RFMi substitution guides is recommended before implementation.
