2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA,

and Rx/Tx/Antenna Diversity Switch

MAX2830

General Description

Features

♦ 2.4GHz to 2.5GHz ISM Band Operation

The MAX2830 direct conversion, zero-IF, RF transceiver

is designed specifically for 2.4GHz to 2.5GHz 802.11g/b

WLAN applications. The MAX2830 completely integrates

all circuitry required to implement the RF transceiver

function, providing an RF power amplifier (PA), an Rx/Tx

and antenna diversity switch, RF-to-baseband receive

path, baseband-to-RF transmit path, voltage-controlled

oscillator (VCO), frequency synthesizer, crystal oscillator,

and baseband/control interface. The MAX2830 includes

a fast-settling sigma-delta RF synthesizer with smaller

than 20Hz frequency steps and a digitally tuned crystal

oscillator allowing use of a low-cost crystal. No I/Q cali-

bration is required; however, the device also integrates

on-chip DC-offset cancellation and I/Q errors and carrier

leakage-detection circuits for improved performance.

Only an RF bandpass filter (BPF), crystal, a pair of

baluns, and a small number of passive components are

needed to form a complete 802.11g/b WLAN RF front-

end solution.

♦ IEEE 802.11g/b Compatible (54Mbps OFDM and

11Mbps CCK)

♦ Complete RF Transceiver, PA, Rx/Tx and Antenna

Diversity Switch, and Crystal Oscillator

Range

60dB Range Analog RSSI per RF Gain Setting

Fast Rx I/Q DC-Offset Settling

Programmable Baseband Lowpass Filter

20-Bit Sigma-Delta Fractional-N PLL with

< 20Hz Step Size

The MAX2830 completely eliminates the need for an

external SAW filter by implementing on-chip monolithic fil-

ters for both the receiver and transmitter. The baseband

filters are optimized to meet the IEEE 802.11g standard

and proprietary turbo modes up to 40MHz channel band-

width. These devices are suitable for the full range of

802.11g OFDM data rates (6Mbps to 54Mbps) and

802.11b QPSK and CCK data rates (1Mbps to 11Mbps).

The ICs are available in a small, 48-pin thin QFN package

measuring only 7mm x 7mm x 0.8mm.
