MAX2358EGI

Overview

The MAX2358EGI is a quadruple-mode RF integrated circuit featuring an integrated low-noise amplifier (LNA) and mixer. It supports dual frequency bands: Cellular (869MHz to 894MHz) and PCS (1.93GHz to 1.99GHz). The device utilizes a 28-TQFN (5x5mm) surface-mount package with exposed pad for thermal dissipation.

Feature Summary

• Integrates LNA and mixer functions in a single compact IC
• Supports multiple gain states including high-gain/high-linearity and ultra-low gain
• Features dedicated IF ports for cellular/PCS and GPS signal routing

Applications

• CDMA cellular handsets
• GSM mobile communication devices
• E911 location assistance systems
• Traveler assistance applications requiring GPS signal processing

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official documentation. Ensure the package matches the specified 28-TQFN dimensions. Confirm that the specific suffix corresponds to the intended tape-and-reel or tray packaging configuration as defined in the product datasheet.

Selection Notes

Select this component for applications requiring simultaneous cellular and PCS band coverage within a single RF front-end path. Consider the available gain states for optimizing dynamic range versus current consumption. Evaluate the exposed pad requirement for proper thermal management during operation.
