RF Transmitter Procurement Notes

Verify the specific suffix 'GMR' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected variant matches the required frequency band and modulation requirements for the target application.

RF Transmitter Selection Notes

Select this component for designs requiring only transmission capabilities without integrated receiving functionality. Consider the 12.5 dBm output power limit when determining antenna requirements. Verify that the SPI interface compatibility aligns with the host microcontroller's available communication ports.

RF Transmitter Part Context

This part belongs to the EZRadioPRO family of wireless transceivers. It represents a simplified transmitter-only variant within the broader SI40xx series, designed to reduce system complexity and cost for applications that do not require two-way communication capabilities.
