The MAX2822 single-chip transceiver is designed for

802.11b (11Mbps) applications operating in the 2.4GHz

to 2.5GHz ISM band. The transceiver includes all the

circuitry required to implement an 802.11b RF-to-base-

band transceiver solution, including the power amplifi-

er, transmit/receive switch, and 50Ω matching. The fully

integrated receive path, transmit path, VCO, frequency

synthesis, and baseband/control interface provide all

the required active RF circuitry. Only a small number of

passive components are needed to form the complete

radio front-end solution.

♦ 2.4GHz to 2.5GHz ISM Band Operation

♦ 802.11b (11Mbps CCK and 22Mbps PBCC) PHY

Compatible

♦ Integrated +17dBm PA

♦ Integrated PA Power Detector

♦ Integrated Transmit/Receive Switch

♦ Complete RF-to-Baseband Transceiver

Direct Up/Down Conversion

Monolithic Low-Phase-Noise VCO

Integrated Baseband Lowpass Filters

Integrated PLL with 3-Wire Serial Interface

Digital Bias Control for PA

Transmit Power Control

Receive Baseband AGC

The IC eliminates the need for external IF SAW and RF

image-reject filters by utilizing a direct-conversion radio

architecture and monolithic baseband filters for both

receiver and transmitter. It is specifically optimized for

802.11b (11Mbps CCK) and 22Mbps PBCC™ applica-

tions. The baseband filtering and Rx and Tx signal

paths support the CCK modulation scheme for BER =

10^-5at the required sensitivity levels.

Complete Baseband Interface

Digital Tx/Rx Mode Control

♦ -95dBm Rx Sensitivity at 1Mbps

♦ -85dBm Rx Sensitivity at 11Mbps

♦ Single +2.7V to +3.0V Supply

♦ 2µA Shutdown Mode

The transceiver is suitable for the full range of 802.11b

data rates (1Mbps, 2Mbps, 5.5Mbps, and 11Mbps) as

well as the higher-rate 22Mbps PBCC standard. The

MAX2822 is available in the very small 7mm x 7mm 48-

lead QFN or thin QFN packages. The small solution size

makes it ideal for small form-factor 802.11b applications

such as PDAs, SmartPhones, and embedded modules.
