Overview
The MAX2825ETN is a single-chip RF transceiver designed for IEEE 802.11b/g wireless LAN applications operating in the 2.4 GHz band. It integrates a direct-conversion transmitter and receiver, synthesizer, and power amplifier driver. The device supports DSSS modulation with data rates up to 11 Mbps. It operates from a single 3.0 V to 3.6 V supply and features an SPI interface for control. The component is housed in a 48-lead TQFN package with an exposed pad for thermal management.
Feature Summary
- Integrates a complete direct-conversion transceiver chain including mixer, filters, and baseband amplifiers
- Includes an on-chip voltage-controlled oscillator (VCO) and fractional-N synthesizer
- Features a low-noise amplifier (LNA) with variable gain control for the receiver path
- Supports standard IEEE 802.11b/g DSSS modulation schemes
Applications
- Wireless Local Area Network (WLAN) access points
- IEEE 802.11b/g compliant network interface cards
- Embedded wireless communication modules
- IoT devices requiring 2.4 GHz connectivity
Procurement Notes
Verify the specific suffix 'ETN' against the manufacturer's current product status page. Confirm RoHS compliance and lead times directly with authorized distributors. Ensure the ordering part number matches the exact package and temperature grade required for your design.
Selection Notes
Select this component for designs requiring a highly integrated solution for 2.11b/g at 2.4 GHz. Evaluate the PCB layout requirements for the exposed thermal pad to ensure adequate heat dissipation. Verify that the system power supply meets the specified voltage range of 3.0 V to 3.6 V.
Part Context
This part belongs to the Maxim Integrated MAX28xx family of WLAN transceivers. It serves as a cost-effective alternative to discrete RF solutions by consolidating multiple functions into a single silicon die. The ETN designation indicates the specific package type and operating temperature range defined by the manufacturer.
Replacement Considerations
Check for updated versions within the MAX28xx series or compatible alternatives from Analog Devices. Ensure any substitute maintains compatibility with 802.11b/g standards and the 2.4 GHz frequency band.
