MAX2900ETI+

RF Transmitter Overview

The MAX2900ETI+ is a complete single-chip transmitter IC designed for the 868MHz and 915MHz ISM bands, specifically compliant with FCC CFR47 part 15.247 specifications for the 902MHz to 928MHz range. It delivers an output power of 20dBm (100mW) within a 28-WFQFN exposed pad package. The device operates on a supply voltage ranging from 2.7V to 4.5V. It integrates essential RF components to minimize external circuitry requirements.

RF Transmitter Feature Summary

• Full integration of transmitter functions to reduce external component count
• Compliance with FCC CFR47 part 15.247 for 902-928MHz ISM band operations
• Supports ASK and OOK modulation schemes for data transmission

RF Transmitter Applications

• Wireless sensor networks in industrial environments
• Remote control systems for consumer electronics
• Telemetry applications requiring short-range data links

RF Transmitter Procurement Notes

Verify that the specific suffix ETI corresponds to the required tape and reel packaging configuration rather than tube packaging when ordering. Confirm that the lead-free status aligns with RoHS directives if environmental compliance is mandatory for your assembly process. Ensure the supplier provides valid origin documentation to guarantee authenticity of the Analog Devices component.

RF Transmitter Selection Notes

Select this component when design constraints require high integration levels to simplify PCB layout and reduce bill of materials complexity. It is suitable for applications needing reliable transmission in the North American ISM bands without complex external matching networks. Consider the 2.7V to 4.5V supply range compatibility with existing system power rails before finalizing the design architecture.

RF Transmitter Part Context

This part belongs to the MAX2900–MAX2904 family of single-chip transmitters. While the MAX2903 and MAX2904 variants target the European 868MHz ISM band per ETSI standards, the MAX2900 series is optimized for the 902-928MHz frequency range. All members share similar architectural features but differ in frequency tuning ranges and regulatory compliance certifications.

RF Transmitter Replacement Considerations

The MAX2901ETI+ serves as a direct functional substitute within the same product family. Both devices share identical pinouts, package dimensions, and electrical characteristics for the 902-928MHz band. Verify that any replacement unit maintains the same surface-mount antenna interface and supply voltage specifications.
