MAX2359EGI

Overview

The MAX2359EGI is a quadruple-mode PCS/Cellular/GPS LNA/Mixer IC from the Maxim Integrated family, optimized for CDMA, GSM, and TDMA applications. It integrates dual signal paths: one for cellular/PCS signals with selectable IF ports, and a dedicated path for GPS signals supporting E911 and traveler assistance. The device operates on a single 3.3V supply, utilizing internal charge pumps to generate ±5V rails. It features a 28-pin TQFN-EP package (5x5mm) and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual signal paths for simultaneous cellular/PCS and GPS processing
• Features internal charge pumps generating ±5V rails from a single 3.3V supply
• Supports multiple LNA configurations to optimize dynamic range at minimum current
• Allows flexible routing of cellular and PCS signals to either IF port

Applications

• CDMA cellular handsets
• GSM mobile communication devices
• TDMA wireless systems
• E911 location services
• Traveler assistance navigation modules

Procurement Notes

Verify that the component matches the specific MAX2359EGI designation within the Analog Devices portfolio. Confirm the package type is TQFN-EP and check for lead-free compliance markings. Ensure the supplier provides valid traceability documentation consistent with Maxim Integrated standards. Cross-reference the datasheet revision to confirm operational parameters align with your design requirements.

Selection Notes

Select this component when designing multi-band mobile terminals requiring integrated LNA and mixer functions for both voice/data and GPS bands. It is suitable for applications needing high integration to reduce board space and power consumption. Consider the single-supply operation and internal voltage generation capabilities for simplified power management designs in compact handheld devices.
