MAX2354ETI

Overview

The MAX2354ETI is a quadruple-mode PCS/Cellular/GPS Low Noise Amplifier and Mixer integrated circuit manufactured by Maxim Integrated. It operates within the frequency range of 869MHz to 1.99GHz. The device utilizes a 28-pin WFQFN exposed pad package with dimensions of 5mm x 5mm and a height of 0.80mm. It supports surface mount mounting and functions as an LNA/Mixer for wireless communication applications.

Feature Summary

• Supports quadruple-mode operation for PCS, Cellular, and GPS bands
• Integrates Low Noise Amplifier and Mixer signal paths
• Optimized for CDMA, GSM, and TDMA applications

Applications

• CDMA cellular systems
• GSM wireless networks
• TDMA communication devices
• E911 location services
• Traveler assistance applications

Procurement Notes

Verify the specific suffix (e.g., ETI vs. ETI+) against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the 28-TQFN package variant matches the target PCB footprint. Confirm lead-free compliance requirements align with the component's environmental certification before procurement.

Selection Notes

Select this component for designs requiring integrated LNA and mixer functionality in a compact form factor. It is suitable for multi-band mobile handsets supporting PCS and cellular frequencies. Consider the 28-pin QFN package constraints for thermal management and layout density when integrating into the system architecture.

Part Context

This part belongs to the MAX235x family of single-chip multi-band LNA/mixers from Maxim Integrated. The family includes variants like MAX2351, MAX2354, MAX2358, and MAX2538. These ICs are designed to simplify RF front-end design by combining multiple functions into a single solution for mobile communication standards.

Replacement Considerations

Direct substitutes include MAX2351ETI, MAX2358ETI, and MAX2530ETI from the same product family. Verify functional equivalence regarding mode support and IF port configurations before substitution.
