2.4GHz to 2.5GHz 802.11g/b

RF Transceivers with Integrated PA

General Description

Features

♦ 2.4GHz to 2.5GHz ISM Band Operation

The MAX2831/MAX2832 direct conversion, zero-IF, RF

transceivers are designed specifically for 2.4GHz to

2.5GHz 802.11g/b WLAN applications. The MAX2831

completely integrates all circuitry required to implement

the RF transceiver function, providing an RF power

amplifier (PA), RF-to-baseband receive path, baseband-

to-RF transmit path, VCO, frequency synthesizer, crystal

oscillator, and baseband/control interface. The MAX2832

integrates the same functional blocks except for the PA.

Both devices include a fast-settling sigma-delta RF syn-

thesizer with smaller than 20Hz frequency steps and a

digitally tuned crystal oscillator allowing use of a low-cost

crystal. The devices also integrate on-chip DC-offset

cancellation and I/Q errors and carrier leakage-detection

circuits. Only an RF bandpass filter (BPF), crystal, RF

switch, 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, and Crystal

Oscillator (MAX2831)

Best-in-Class Transceiver Performance

62mA Receiver Current

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

Digitally Tuned Crystal Oscillator

+18.5dBm Transmit Power (5.6% EVM with

54Mbps OFDM)

The MAX2831/MAX2832 completely eliminate the need

for an external SAW filter by implementing on-chip mono-

lithic filters 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 bandwidth. 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 TQFN

package measuring only 7mm x 7mm x 0.8mm.

Applications

♦ Transceiver Operates from +2.7V to +3.6V

♦ PA Operates from +2.7V to +4.2V (MAX2831)

♦ Low-Power Shutdown Mode

Wi-Fi, PDA, VOIP, and Cellular Handsets

Wireless Speakers and Headphones

General 2.4GHz ISM Radios

♦ Small 48-Pin TQFN Package
