MAX2009ETI-T

Overview

The MAX2009ETI-T is an integrated RF front-end component manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a TQFN-28 package measuring 5x5 mm with a height of 0.80 mm. It operates within a frequency range of 1.2 GHz to 2.5 GHz and supports a minimum operating temperature of -40°C and a maximum of +85°C. The device provides up to 7 dB of gain expansion and 24° of phase expansion as input power increases. It is designed for wireless communication systems requiring linearization capabilities.

Feature Summary

• Provides adaptive gain and phase expansion to correct amplifier non-linearities
• Integrated radio frequency front-end solution for system simplification
• Optimized for operation across wideband cellular and PCS frequency ranges

Applications

• Wireless communication systems
• Cellular base station linearization
• PCS band signal processing

Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as supply constraints may apply. Confirm that the specific suffix matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS directives and check for any regional distribution restrictions before finalizing procurement plans.

Selection Notes

Select this component when designing RF chains requiring built-in linearization without external predistortion circuits. Evaluate the 1.2 GHz to 2.5 GHz operational bandwidth against system requirements. Consider the thermal performance limits between -40°C and +85°C for environmental suitability.

Part Context

This part belongs to the Maxim Integrated RF front-end family, specifically engineered for linearization applications. It integrates functionality typically requiring separate components, reducing board space and design complexity. The device targets high-performance wireless infrastructure where signal fidelity is critical.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may not replicate the specific 7 dB gain and 24° phase expansion characteristics.
