RF Transmitter Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to discontinuation notices. Confirm that the specific ordering suffix matches the required tape-and-reel packaging format. Ensure compatibility with existing design specifications regarding voltage levels and modulation requirements before finalizing procurement orders.

RF Transmitter Selection Notes

Select this component for designs requiring simple ASK or FSK transmission at 315 MHz. Consider the 16-TSSOP package constraints for layout planning. Evaluate if the integrated antenna interface meets impedance matching requirements without external components. Compare against other models in the series for pinout and feature variations.

RF Transmitter Part Context

This component belongs to the TDK510x family of RF transmitters from Infineon Technologies. It shares functional similarities with the TDK5100 but differs in operating frequency bands. The XUMA1 suffix indicates a specific reel-based packaging configuration used for high-volume surface-mount assembly processes.
