MAX2359ETI+T

Overview

The MAX2359ETI+T is an RF integrated circuit functioning as a Low Noise Amplifier (LNA) and mixer, designed for PCS band applications. It operates within a frequency range of 1.93GHz to 1.99GHz and supports quadruple-mode operation. The device is housed in a 28-TQFN package with dimensions of 5x5 mm and features an exposed pad for thermal management. It is rated for surface mount installation and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates low noise amplification and mixing capabilities for RF signal processing
• Supports quadruple-mode operation for flexible system configuration
• Optimized for PCS band frequency ranges

Applications

• PCS band wireless communication systems
• RF front-end modules requiring LNA and mixer integration
• Quadruple-mode RF transceiver architectures

Procurement Notes

Verify component status carefully as this part is marked obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market sources if procurement is required. Ensure compatibility with existing PCB layouts due to the specific 28-TQFN package requirements. Check for any product change notices or end-of-life notifications prior to finalizing design-in decisions.

Selection Notes

Select this component only for designs specifically targeting PCS band frequencies between 1.93GHz and 1.99GHz. The quadruple-mode functionality offers flexibility but requires careful impedance matching and biasing considerations. Due to its obsolete status, consider long-term supply chain risks and potential need for redesign if future production scaling is anticipated. Verify thermal performance requirements given the QFN package constraints.

Part Context

This device belongs to the Maxim Integrated RF IC family, specifically designed for wireless communication applications. It combines LNA and mixer functions into a single compact package, reducing board space compared to discrete solutions. The 28-TQFN form factor provides efficient thermal dissipation through the exposed pad, suitable for dense PCB layouts in mobile and base station equipment.

Replacement Considerations

As the MAX2359ETI+T is obsolete, direct substitutes may be limited. Review Analog Devices' current RF LNA/mixer portfolio for compatible alternatives. Evaluate pin-to-pin replacements or functional equivalents that support similar PCS band frequencies and quadruple-mode operations. Consult official replacement guides from the manufacturer for validated cross-reference options.
