2.4GHz 802.11b Zero-IF Transceivers

General Description

Features

The MAX2820/MAX2820A and MAX2821/MAX2821A

single-chip zero-IF transceivers are designed for the

802.11b (11Mbps) applications operating in the

2.4GHz to 2.5GHz ISM band. The transceivers are

nearly identical, except the MAX2821 and MAX2821A

also provide a low-power shutdown mode and an ana-

log voltage reference output. The MAX2820A/

MAX2821A are cost-reduced versions, virtually identi-

cal in pinout and performance to the MAX2820/

MAX2821. The transceivers include all the circuitry

required to implement an 802.11b RF-to-baseband

transceiver solution, 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

Digital Tx/Rx Mode Control

Analog Receive Level Detection

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.

ꢀ -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 and MAX2821 are available in a 7mm × 7mm

48-lead QFN package. The MAX2820, MAX2821,

MAX2820A, and MAX2821A are available in a 48-lead

thin QFN package.

ꢀ Low-Current Shutdown Mode (MAX2821 only)

ꢀ Very Small 48-Pin QFN Package(s)
