MAX2820ETM+

RF Transceiver ICS Overview

The MAX2820ETM+ is a single-chip RF transceiver designed for 802.11b wireless LAN applications operating in the 2.4 GHz to 2.4835 GHz frequency range. It integrates a transmitter and receiver within a compact 48-lead TQFN package. The device supports data rates up to 11 Mb/s and operates on a single 3.0 V to 3.6 V power supply. Key electrical specifications include a maximum output power of 15 dBm, a noise figure of 6.5 dB, and an IP1dB of -1 dBm. It features a serial interface for control and configuration.

RF Transceiver ICS Feature Summary

• Integrates both transmitter and receiver functions into a single silicon chip for simplified system design.
• Supports direct sequence spread spectrum (DSSS) modulation required by IEEE 802.11b standards.
• Includes integrated voltage-controlled oscillators (VCOs) and synthesizers to reduce external component count.
• Features a serial control interface for flexible configuration of gain, filtering, and operational modes.

RF Transceiver ICS Applications

• Wireless Local Area Network (WLAN) access points
• 802.11b compliant wireless routers
• Industrial wireless sensor networks
• Embedded communication modules

RF Transceiver ICS Procurement Notes

Verify current availability status as this component may be subject to limited supply or end-of-life notifications from Analog Devices. Confirm that the specific suffix ETM+ matches the required lead frame and tape-and-reel or tube packaging options for your assembly process. Ensure compatibility with existing board layouts regarding the 48-TQFN exposed pad thermal requirements.

RF Transceiver ICS Selection Notes

Select this component when designing systems requiring full compliance with IEEE 802.11b standards at 2.4 GHz. It is suitable for applications needing moderate output power and low noise performance without complex external filtering. Consider the TQFN-48 package size constraints and thermal dissipation capabilities during PCB layout planning.

RF Transceiver ICS Part Context

The MAX2820 belongs to Maxim Integrated's family of RF transceivers targeting short-range wireless communications. It serves as a foundational component for legacy Wi-Fi infrastructure and IoT devices requiring robust DSSS connectivity. The device represents a highly integrated solution compared to discrete RF front-end designs.

RF Transceiver ICS Replacement Considerations

Check for official obsolescence notices from Analog Devices. Potential alternatives may include newer generations of 802.11b/g/n transceivers if pin compatibility allows, though functional differences in protocol support must be evaluated carefully.
