2.4GHz 802.11b Zero-IF Transceivers

General Description

Features

The MAX2820/MAX2821 single-chip zero-IF transceivers

are designed for the 802.11b (11Mbps) applications

operating in the 2.4GHz to 2.5GHz ISM band. The trans-

ceivers are nearly identical, except the MAX2821 pro-

vides a low-power shutdown mode and an analog

voltage reference output feature and the MAX2820 does

not. The transceivers include all the circuitry required to

implement an 802.11b RF-to-baseband transceiver solu-

tion, providing a fully integrated receive path, transmit

path, VCO, frequency synthesis, and baseband/control

interface. Only a PA, RF switch, RF BPF, and 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

ꢀ Complete RF-to-Baseband Transceiver

Direct-Conversion Upconverters and

Downconverters

Monolithic Low-Phase-Noise VCO

Integrated Baseband Lowpass Filters

Integrated PLL with 3-Wire Serial Interface

Digital Bias Control for External PA

Transmit Power Control (Range > 25dB)

Receive Baseband AGC (Range > 65dB)

Complete Baseband Interface

The ICs eliminate the need for external IF and base-

band filters by utilizing a direct-conversion radio archi-

tecture and monolithic baseband filters for both

receiver and transmitter. They are specifically opti-

mized for 802.11b (11Mbps CCK) applications. The

baseband filtering and RX and TX signal paths support

the CCK modulation scheme for BER = 10^-5at the

required sensitivity levels.

Digital TX/RX Mode Control

Analog Receive Level Detection

ꢀ -97dBm RX Sensitivity at 1Mbps

ꢀ -87dBm RX Sensitivity at 11Mbps

ꢀ +2dBm Transmit Power (11Mbps CCK)

ꢀ Single +2.7V to +3.6V Supply

The devices are suitable for the full range of 802.11b

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

also the higher-rate 22Mbps PBCC^TMstandard. The

MAX2820/MAX2821 are available in the very small 7mm

× 7mm 48-lead QFN package.

ꢀ Low-Current Shutdown Mode (MAX2821 only)

ꢀ Very Small 48-Pin QFN Package (s)
