• Integrates a programmable synthesizer and high-performance receiver chain for reliable signal processing.
• Features low-power design capabilities suitable for battery-operated applications.

RF Transmitter Applications

• Wireless remote control systems
• Industrial monitoring and automation
• Smart metering infrastructure

RF Transmitter Procurement Notes

Verify the specific suffix 'FMR' corresponds to the tape-and-reel packaging configuration required for surface-mount assembly processes. Confirm that the part status indicates availability or obsolescence status prior to integration into new designs, as this component may be designated as not recommended for new designs.

RF Transmitter Selection Notes

Select this component when only transmission capability is required for sub-GHz ISM band applications. Compare against transceiver models like the SI4463 if bidirectional communication is necessary. Ensure the 20dBm output power meets link budget requirements for the intended antenna configuration and distance.

RF Transmitter Part Context

This transmitter is part of the broader EZRadioPRO family, which includes various transceivers and receivers from Silicon Labs. It shares architectural similarities with other devices in the series but lacks receive functionality. It serves as a specialized solution for simple uplink telemetry or command transmission scenarios.

RF Transmitter Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Silicon Labs selection guides for compatible alternatives within the EZRadioPRO portfolio.
