MAX2022ETX+T

Overview

The MAX2022ETX+T is a high-dynamic-range quadrature modulator/demodulator designed for direct up/downconversion in the 1.5GHz to 3GHz frequency range. It supports CDMA2000, DCS1800, WCDMA, and UMTS applications. The device integrates a modulator and demodulator within a single integrated circuit, facilitating efficient signal processing for multi-carrier communications transmitters. Packaged in a 36-TQFN (6x6) surface-mount enclosure, it operates with RoHS3 compliance and features a moisture sensitivity level of 1.

Feature Summary

• Integrates quadrature modulation and demodulation functions for direct conversion architectures
• Supports multiple wireless standards including CDMA2000, DCS1800, WCDMA, and UMTS
• Optimized for high-dynamic-range performance in multi-carrier transmitter applications

Applications

• Multi-carrier communications transmitters
• WCDMA/UMTS base station and mobile equipment
• CDMA2000 and DCS1800 RF front-end modules

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package marking matches the 36-TQFN specification. Check datasheet revisions for any layout guideline updates. Ensure storage conditions comply with MSL Level 1 requirements prior to soldering. Validate supply chain documentation against Analog Devices official records.

Selection Notes

Select this component for designs requiring integrated up/downconversion in the 1.5GHz to 3GHz band. It is suitable for applications supporting CDMA2000, DCS1800, WCDMA, and UMTS protocols. Consider the 36-TQFN footprint for PCB space constraints. Evaluate thermal management needs for multi-carrier transmitter environments. Ensure system architecture aligns with direct conversion topology requirements.

Part Context

This part belongs to the MAX2022 family of RF modulators/demodulators from Analog Devices/Maxim Integrated. It shares functional similarities with the MAX2023 but differs in supported frequency ranges and specific standard optimizations. The ETX+ suffix indicates a lead-free, RoHS-compliant variant in a TQFN package. It serves as a key building block for modern wireless infrastructure and mobile devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts and firmware if considering alternative RF ICs. Consult Analog Devices application notes for general layout guidelines when transitioning between similar RF components.
