RF Transmitter Procurement Notes

Verify the specific suffix C2R against official manufacturer documentation to confirm tape-and-reel packaging specifications and any unique handling requirements. Ensure compatibility with the intended PCB footprint and thermal management strategy for the TQFN-EP-16 package. Cross-reference the RoHS status and lead-free compliance details directly with the latest datasheet revision to meet regulatory standards for your target market.

RF Transmitter Selection Notes

Select this component when a compact, low-power solution is required for sub-GHz wireless communication. The fixed 10 dBm output power suits short-to-medium range applications without external amplifiers. Consider the wide operating temperature range for harsh environments. Evaluate the crystal-based design against direct digital synthesis alternatives if phase noise performance is critical for the specific protocol.

RF Transmitter Part Context

This part belongs to the MAX1479 family of low-power RF transmitters designed for simple, cost-effective wireless links. The series focuses on minimizing power consumption while maintaining reliable transmission in the ISM bands. The ATE+ designation indicates a specific pinout and package variant within the broader product line, ensuring interchangeability with other devices in the same functional family where applicable.
