MAX2829ETN

RF Transceiver ICS Overview

The MAX2829ETN is a single-chip RF transceiver supporting 802.11a/b/g protocols for WiFi applications. It operates across dual bands: 2.4GHz and 5GHz (specifically 2.412GHz to 5.875GHz). The device supports data rates up to 54Mbps using CCK, DSSS, and OFDM modulation schemes. Key electrical parameters include a transmit power of -2dBm and a receive sensitivity of -75dBm. Supply voltage ranges from 2.7V to 3.6V. Receive current varies between 118mA and 210mA, while transmit current ranges from 142mA to 157mA. It utilizes an SPI serial interface and is housed in a 56-WFQFN package with an exposed pad.

RF Transceiver ICS Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact packaging and tape-and-reel specifications. Ensure the procurement source provides valid RoHS compliance certificates as required by ECCN 5A991G regulations. Confirm that the supplier offers genuine Maxim Integrated products to avoid counterfeit components. Check for updated lead times due to potential supply chain fluctuations. Validate that the received units match the 56-TQFN(8x8) physical dimensions specified in the datasheet.

RF Transceiver ICS Selection Notes

Select this component when designing systems requiring integrated dual-band WiFi connectivity without external front-end modules. Consider the 56-WFQFN package size for space-constrained PCB layouts. Evaluate the power consumption profiles against battery life requirements, noting the distinct current draw for receive versus transmit modes. Ensure the host microcontroller supports the required SPI interface for control and configuration. Verify thermal management capabilities given the exposed pad requirement for heat dissipation.

RF Transceiver ICS Part Context

The MAX2829 belongs to the MAX2828/MAX2829 family of world-band transceivers designed by Maxim Integrated, now part of Analog Devices. These chips are engineered to replace discrete RF solutions, reducing bill-of-materials complexity. The ETN variant specifically denotes the TQFN package form factor. This series targets cost-sensitive WiFi markets where integration density is critical for miniaturization of end-user devices.
