RF Transmitter Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official documentation as '+T' denotes lead-free and halogen-free construction. Ensure the supplier provides valid traceability records for automotive-grade components if required by your application standards.

RF Transmitter Selection Notes

Select this component for applications requiring fixed frequency operation at 315MHz or 390MHz without complex modulation requirements. It is suitable for designs prioritizing low BOM cost and minimal external component count. Consider the 24-TQFN footprint for PCB layout constraints and ensure adequate thermal management due to the exposed pad design.
