Analog Devices Inc./Maxim Integrated MAX2821ETM- is a highly integrated RF transceiverIC designed for 802.11b wireless applications. This component operates exclusively as a transmitter/receiver, supporting CCK modulation at 2.4GHz with a maximum data rate of 22Mbps. It features a highly sensitive receiver with a sensitivity of -97dBm and provides a transmit power output of +3dBm. The device is controlled via an SPI serial interface and requires a supply voltage ranging from 2.7V to 3.6V. Typical current consumption during receive is 80mA, and during transmit is 70mA. The MAX2821ETM- is supplied in a 48-WFQFN exposed pad package, suitable for surface mounting in demanding environments. This transceiver finds application in wireless networking, consumer electronics, and industrial automation where robust 802.11b connectivity is essential.
