MAX2321EUP+T

Overview

The MAX2321EUP+T is a dual-band Low Noise Amplifier and Mixer manufactured by Analog Devices Inc./Maxim Integrated. It utilizes Silicon Germanium (SiGe) technology to provide adjustable gain characteristics for RF signal processing. The device operates across two distinct frequency bands: 800 MHz to 1 GHz and 1.8 GHz to 2.5 GHz. It is housed in a 20-TSSOP package with an exposed pad, designed for surface mount installation. This component supports multiple cellular communication standards, integrating LNA and mixer functions into a single compact solution.

Feature Summary

• Integrates Low Noise Amplifier and Mixer functions using SiGe technology
• Supports dual-band operation covering 800 MHz–1 GHz and 1.8 GHz–2.5 GHz
• Features adjustable gain capabilities for flexible system design

Applications

• Cellular communication systems supporting multiple standards
• RF front-end modules requiring combined amplification and mixing
• Wireless infrastructure equipment operating in specified frequency bands

Procurement Notes

Verify the specific suffix and tape/reel packaging details against the manufacturer's official documentation before procurement. Confirm that the 20-TSSOP exposed pad footprint matches your PCB layout requirements. Ensure compatibility with the intended cellular standards and frequency bands for your specific application design.

Selection Notes

Select this component when a combined LNA and mixer solution is required for dual-band cellular applications. Consider the SiGe technology benefits for noise performance and the adjustable gain feature for system optimization. Verify that the 20-TSSOP package size fits within the spatial constraints of the target hardware design.

Part Context

This part belongs to the Maxim Integrated RF amplifier and mixer portfolio, specifically designed for wireless communications. It represents a consolidated solution for RF front-end stages, reducing component count compared to discrete implementations. The dual-band capability allows it to serve various cellular protocols within its operational frequency ranges.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family or newer revisions from Analog Devices/Maxim Integrated. Verify electrical parameter equivalence for both frequency bands and gain settings before substitution.
