MAX2354EGI

Overview

The MAX2354EGI is a quadruple-mode PCS/Cellular/GPS Low Noise Amplifier (LNA) and mixer IC from Maxim Integrated. It integrates dual LNAs and mixers optimized for CDMA, GSM, and TDMA applications in cellular and PCS bands. The device features a dedicated GPS LNA/mixer signal path for E911 and traveler assistance. It supports routing cellular and PCS signals to either of two IF ports with varying bandwidths, while the GPS band utilizes its own IF port. Packaged in a 28-pin TQFN (5x5mm), it operates between -40°C and +85°C.

Feature Summary

• Integrates dual LNAs and mixers for simultaneous multi-band processing
• Features a dedicated GPS signal path separate from cellular/PCS channels
• Supports flexible IF output routing for variable bandwidth filtering

Applications

• CDMA cellular and PCS receiver front-ends
• GSM and TDMA mobile communication systems
• E911 location services and traveler assistance modules

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Ensure the package matches the 28-pin TQFN form factor. Confirm that the part number suffix corresponds to the standard lead-free RoHS-compliant variant. Request original manufacturer documentation or authorized distributor certificates to validate supply chain integrity before integration.

Selection Notes

Select this component when designing receivers requiring integrated amplification and frequency conversion for multiple wireless standards. It is suitable for applications needing distinct signal paths for GPS navigation alongside voice/data bands. Consider the thermal performance within the specified operating temperature range and ensure the PCB layout accommodates the small QFN footprint for optimal RF performance.
