MAX2902EGI

RF Transmitter Overview

The MAX2902EGI is a single-chip RF transmitter IC designed for the 868MHz and 915MHz ISM bands. It delivers 200mW output power and complies with FCC CFR47 Part 15.247 specifications for the 902MHz to 928MHz range. The device features full integration of the transmitter circuitry, minimizing external component requirements. It operates within a temperature range of -40°C to +85°C and utilizes a QFN-28 (5mm x 5mm) package.

RF Transmitter Feature Summary

• Full integration of transmitter circuitry to minimize external components
• Compliance with FCC CFR47 Part 15.247 ISM-band specifications
• Designed for operation in 868MHz/915MHz frequency bands

RF Transmitter Applications

• ISM band wireless communication systems
• FCC-compliant RF transmitter designs
• Single-chip transmitter solutions for 902MHz to 928MHz applications

RF Transmitter Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated or Rochester Electronics, LLC, depending on the supply channel. Confirm the package type is QFN-28 (5x5mm) and ensure the operating temperature range meets the -40°C to +85°C requirement. Cross-reference the part number against official datasheets to confirm compliance with FCC CFR47 Part 15.247 standards before procurement.

RF Transmitter Selection Notes

Select this component for applications requiring a complete single-chip solution for 868MHz/915MHz ISM bands. It is suitable where FCC compliance for the 902-928MHz range is mandatory. Consider the high level of integration which reduces bill-of-materials complexity. Ensure the design supports the QFN-28 thermal and electrical interface requirements.

RF Transmitter Part Context

The MAX2902EGI belongs to the MAX2900–MAX2904 family of 200mW single-chip transmitters. This series is engineered for high integration in ISM band applications. The MAX2902 specifically targets the North American ISM band regulations, distinguishing it from variants like the MAX2903/MAX2904 which comply with ETSI EN330-220 for the European 868MHz band.

RF Transmitter Replacement Considerations

The MAX2900EGI and MAX2901EGI are related parts within the same family. However, specific functional equivalence or direct substitution requires verification against the target regulatory compliance (FCC vs. ETSI) and exact frequency band requirements defined in the official documentation.
