MAX2358ETI

Overview

The MAX2358ETI is a quadruple-mode PCS/Cellular/GPS Low Noise Amplifier and Mixer integrated circuit from the MAX235 family. It operates in the cellular band (869MHz to 894MHz) and the PCS band (1.93GHz to 1.99GHz). The device is housed in a 28-TQFN package measuring 5mm by 5mm with an exposed pad. It is designed for CDMA, GSM, and TDMA applications in mobile phones.

Feature Summary

Integrates dual-band LNA and mixer functionality for cellular and PCS frequencies within a single compact surface-mount package.
Supports multiple operational states including high gain/high linearity, midgain, and ultra-low gain to optimize dynamic range at minimum current consumption.
Features independent signal routing capabilities allowing cellular and PCS signals to be directed to separate IF ports for flexible filter configuration.

Applications

CDMA mobile phone front-end modules
GSM wireless communication devices
TDMA cellular handsets
E911 location assistance systems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to discontinuation status. Confirm package integrity upon receipt as the device utilizes a fine-pitch QFN form factor sensitive to handling. Ensure storage conditions comply with moisture sensitivity levels specified in the official datasheet to prevent soldering defects during assembly.

Selection Notes

Select this component for designs requiring simultaneous cellular and PCS band support with GPS capability. Evaluate the specific IF port requirements against the available bandwidth options. Consider the trade-off between gain states and power consumption when defining the system's dynamic range needs for target network standards.

Part Context

This part belongs to the MAX235 series of RF front-end ICs optimized for multi-mode wireless applications. It shares architectural similarities with the MAX2351, MAX2354, and MAX2359, offering comparable LNA/mixer integration. The series targets the transition era of dual-band mobile handsets requiring robust signal processing for both legacy and emerging cellular standards.
