MAX2537ETI

Overview

The MAX2537ETI is a quadruple-mode RF mixer and low-noise amplifier (LNA) integrated circuit designed for PCS, cellular, and GPS applications. It operates in the 869–894 MHz cellular band, 1930–1990 MHz PCS band, and 1575.42 MHz GPS band. The device features two IF ports to support flexible filtering configurations and includes a dedicated signal path for E911 and traveler assistance. Packaged in a 28-pin TQFN (5x5 mm) with exposed pad, it supports operation from -40°C to +85°C.

Feature Summary

Supports quadruple-mode operation across cellular, PCS, and GPS frequency bands
Features dual IF ports for independent bandwidth filtering configuration
Includes dedicated GPS LNA/mixer signal path for location-based services

Applications

CDMA cellular handsets
GSM mobile devices
E911 emergency location systems
Traveler assistance navigation modules

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official Maxim Integrated documentation. Ensure the package matches the specified 28-pin TQFN form factor. Confirm that the suffix indicates the standard tape-and-reel or tube packaging variant as required by your assembly process. Cross-reference the date code with current production status to ensure availability.

Selection Notes

Select this component when designing multi-band receivers requiring integrated LNA and mixing functions. It is suitable for applications needing separate IF outputs for different bandwidth requirements. Consider the thermal performance of the exposed pad design for high-density PCB layouts. Verify compatibility with the target system's supply voltage and interface requirements.

Part Context

This part belongs to the MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/MAX2531/MAX2537/MAX2538 family of single-die multi-band LNA/mixers. These ICs are optimized for CDMA, GSM, and TDMA applications in both cellular and PCS bands. The family provides a consolidated solution for front-end RF processing in mobile communication devices.

Replacement Considerations

Compatible substitutes within the same family include MAX2538ETI+, MAX2531EGI+, and MAX2351ETI. Verify pinout compatibility and specific mode support before substitution. Ensure the replacement part meets the same environmental temperature range and package dimensions.
