• European regulatory compliant wireless transmitters
• Low-component-count RF designs

RF Transmitter Procurement Notes

Verify current availability status as this component may be obsolete or discontinued. Confirm that the specific suffix denotes compliance with ETSI standards rather than FCC specifications. Ensure the QFN-28 package matches your PCB footprint requirements before procurement.

RF Transmitter Selection Notes

Select this part for applications requiring strict adherence to European 868MHz ISM regulations. It is suitable for designs prioritizing minimal external passive components. Consider thermal management due to the integrated 200mW output capability in a compact QFN package.

RF Transmitter Part Context

This component belongs to the MAX2900-MAX2904 series of single-chip transmitters. While the MAX2900/2901/2902 comply with FCC CFR47 Part 15.247 for the 902-928MHz band, the MAX2903 variant is specifically tuned and certified for the European 868MHz frequency range.
