MAX2389EGC

Overview

The MAX2389EGC is a W-CDMA Low-Noise Amplifier (LNA) and downconverter mixer IC designed for ARIB, ETSI-UMTS, and IMT2000 applications. It operates from a single 2.7V to 3.3V supply. The device features an IF frequency range of 150MHz to 400MHz. Key electrical parameters include a gain of 15dB and a P1dB of -10.5dBm. It minimizes current consumption by omitting the LO buffer.

Feature Summary

• Ultra-low current consumption design optimized for cellular phone power efficiency
• Integrated LNA and downconverter mixer with exceptionally low noise figures
• Supports both single-ended and differential interface configurations
• Includes gain control functionality for signal optimization

Applications

• W-CDMA cellular communication systems
• ARIB standard compliant devices in Japan
• ETSI-UMTS mobile terminals
• IMT2000 infrastructure equipment

Procurement Notes

Verify the specific suffix 'EGC' against official Analog Devices documentation to confirm package type and temperature range specifications. Ensure compatibility with existing RF front-end designs regarding the 150MHz to 400MHz IF range. Confirm that the single-supply voltage requirements align with system power rails before procurement.

Selection Notes

Select this component for applications requiring minimal current draw without an external LO buffer. It is suitable for UMTS handsets needing integrated amplification and mixing. Consider the ultra-small footprint constraints and the specific IF frequency window when designing the intermediate frequency stage of the receiver chain.

Part Context

The MAX2389 belongs to a family including the MAX2387 and MAX2388, all designed for W-CDMA applications. These devices are characterized by their integration of LNA and mixer functions into a single ultra-small package. The series targets mobile phones requiring high performance with strict power limitations.

Replacement Considerations
