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)

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