MAX2827ETN

Overview

The MAX2827ETN is a direct-conversion transceiver IC designed for IEEE 802.11a/b/g wireless LAN applications, supporting both 2.4 GHz and 5 GHz frequency bands. It integrates a transmitter with a synthesizer, a receiver with a synthesizer, and a baseband interface. The device operates on a single 3.0V to 3.6V supply voltage and utilizes a 48-lead TQFN package with an exposed pad for thermal management.

Feature Summary

• Integrates dual-band RF transceiver functionality for 802.11a/b/g compliance
• Includes on-chip synthesizers for both transmit and receive paths
• Features a dedicated baseband interface for simplified system integration

Applications

• Wireless LAN access points
• Wireless LAN client devices
• IEEE 802.11a/b/g compliant systems

Procurement Notes

Verify the specific suffix ETN against the manufacturer's current datasheet to confirm pinout and package dimensions. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure the supplier provides valid traceability documentation for this Analog Devices component.

Selection Notes

Select this component when designing systems requiring integrated dual-band support for legacy Wi-Fi standards. Consider the TQFN package size and thermal requirements during PCB layout. Verify that the host processor can interface correctly with the specified baseband control signals.

Part Context

This part belongs to the MAX282x family of direct-conversion transceivers from Analog Devices (formerly Maxim Integrated). These components are engineered to reduce external component counts in wireless LAN designs by integrating critical RF blocks into a single silicon solution.

Replacement Considerations

Consult official cross-reference tools for verified substitutes. Common alternatives within the same product line include the MAX2829 series.
