MAX2904EGI

RF Transmitter Overview

The MAX2904EGI is a single-chip transmitter IC designed for the European 868MHz ISM band, compliant with ETSI EN330-220 specifications. It delivers up to 200mW output power and supports ASK, BPSK, FM, and OOK modulation schemes. The device operates within an input frequency range of 868MHz to 915MHz, providing a transmit power level between 21dBm and 25dBm. It features a maximum data rate of 1.22Mbps and utilizes a 28-pin VFQFN package with an exposed pad for thermal management.

RF Transmitter Feature Summary

• Complete single-chip integration for simplified design
• Supports multiple modulation formats including ASK, BPSK, FM, and OOK
• Compliant with European ETSI EN330-220 standards
• High output power capability up to 200mW

RF Transmitter Applications

• European 868MHz ISM band telemetry systems
• Wireless sensor networks
• Remote control applications
• Low-power wireless communication devices

RF Transmitter Procurement Notes

Verify that the specific MAX2904 variant meets ETSI EN330-220 requirements for the 868MHz band, as other models in the series target different regions. Confirm the QFN-28 package orientation and exposed pad soldering requirements during assembly. Ensure compatibility with the intended modulation scheme and data rate specifications for the target application.

RF Transmitter Selection Notes

Select the MAX2904EGI specifically for European market compliance due to its adherence to ETSI EN330-220. Consider the MAX2900 or MAX2901 if FCC CFR47 Part 15.247 compliance for the 902-928MHz band is required instead. Evaluate the need for external components based on the high integration level, which minimizes bill-of-materials complexity compared to discrete solutions.

RF Transmitter Part Context

The MAX2904EGI belongs to the MAX2900–MAX2904 family of complete single-chip transmitters. This series is engineered for 868MHz and 915MHz ISM bands, offering varying regional compliance options. The MAX2904 specifically addresses European regulatory standards, distinguishing it from counterparts designed for North American or global markets within the same product line.

RF Transmitter Replacement Considerations

For direct functional replacement in European 868MHz applications, verify availability of the MAX2904EVI or other suffix variants within the same family. Cross-reference pinouts and thermal characteristics to ensure mechanical compatibility. Note that MAX2900/2901/2902 are not suitable replacements due to differing regional compliance certifications.
