MAX2820ETM

RF Transceiver ICS Overview

The MAX2820ETM is a single-chip RF transceiver designed for 802.11b wireless local area network applications operating in the 2.4 GHz ISM band. It integrates a zero-IF architecture to support data rates up to 22 Mbps with CCK modulation. The device features a receive sensitivity of -97 dBm and an output power of 3 dBm. It operates on a supply voltage range of 2.7 V to 3.6 V, drawing 80 mA during reception and 70 mA during transmission. The component is housed in a 48-WFQFN package with exposed pad and supports serial SPI interface control.

RF Transceiver ICS Feature Summary

• Integrates zero-IF receiver and transmitter architectures for simplified system design
• Supports 802.11b protocol with CCK modulation schemes
• Provides integrated frequency synthesizer and baseband filtering
• Features low-power operation suitable for battery-powered devices

RF Transceiver ICS Applications

• Wireless LAN (WLAN) access points
• 802.11b compliant wireless peripherals
• Industrial wireless sensor networks
• Consumer IoT devices requiring 2.4 GHz connectivity

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and lot traceability upon receipt. Check for obsolescence notices as this part may be discontinued or superseded by newer generations. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

RF Transceiver ICS Selection Notes

Select this component for applications requiring certified 802.11b compatibility at 2.4 GHz. Consider the 48-WFQFN package size for space-constrained PCB layouts. Evaluate thermal performance given the exposed pad requirement for heat dissipation. Compare power consumption metrics against newer alternatives if extended battery life is critical. Verify interface compatibility with host microcontrollers supporting SPI protocols.

RF Transceiver ICS Part Context

The MAX2820 belongs to Maxim Integrated's family of zero-IF RF transceivers targeting IEEE 802.11b standards. It serves as a foundational solution for early-generation Wi-Fi devices, preceding more advanced multi-standard chips. The ETM suffix indicates a specific temperature grade and packaging variant within the MAX2820 series, distinct from tape-and-reel options like the MAX2820ETM+T.
