2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA,  
and Rx/Tx/Antenna Diversity Switch  
MAX2830  
General Description  
Features  
o 2.4GHz to 2.5GHz ISM Band Operation  
o IEEE 802.11g/b Compatible (54Mbps OFDM and  
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.  
11Mbps CCK)  
o Complete RF Transceiver, PA, Rx/Tx and Antenna  
Diversity Switch, and Crystal Oscillator  
Best-in-Class Transceiver Performance  
62mA Receiver Current  
3.3dB Rx Noise Figure  
-75dBm Rx Sensitivity (54Mbps OFDM)  
No I/Q Calibration Required  
0.1dB/0.35° Rx I/Q Gain/Phase Imbalance  
33dB RF and 62dB Baseband Gain Control  
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 TQFN package  
measuring only 7mm x 7mm x 0.8mm.
