MAX2538ETI-B6A

Overview

The MAX2538ETI-B6A is a single-chip RF mixer and low-noise amplifier (LNA) from the MAX2538 family, designed for PCS, cellular, and GPS applications. It integrates four distinct signal paths optimized for CDMA, GSM, and TDMA standards. The device features dual IF ports for cellular/PCS signals and a dedicated port for GPS, allowing flexible bandwidth configuration. Operating within a supply voltage range of 2.7V to 3.3V, it consumes 32mA of current. The component utilizes a 28-pin TQFN package measuring 5x5 mm with a height of 0.80 mm, supporting operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates LNA and downconverter functions for multiple wireless standards
• Provides separate signal paths for cellular/PCS and GPS bands
• Supports dual independent IF outputs for flexible filtering

Applications

• CDMA cellular handsets
• GSM mobile communication devices
• E911 location services in mobile phones
• GPS traveler assistance systems

Procurement Notes

Verify the specific suffix B6A against official Analog Devices documentation to confirm tape-and-reel packaging and availability status. Cross-reference the manufacturer part number with distributor listings to ensure compatibility with existing inventory or design requirements. Confirm RoHS compliance and lead times directly with authorized suppliers prior to ordering.

Selection Notes

Select this component when designing receivers requiring integrated LNA and mixer functionality for PCS and cellular bands. It is suitable for applications needing simultaneous support for E911 and GPS assistance. Consider the dual-IF architecture if independent bandwidth optimization for different signal types is required within a single channel.

Part Context

The MAX2538ETI-B6A belongs to the MAX2530/MAX2531/MAX2537/MAX2538 family of single-die multi-band LNAs and mixers. These ICs are optimized for mobile phone front-end modules, providing high dynamic range at minimum current consumption. The family supports various wireless protocols including CDMA, GSM, and TDMA, making them versatile for global mobile communication designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other members of the MAX2538 family, such as MAX2538ETI+, ensuring pinout and electrical specifications match the design requirements.
