2.4GHz to 2.5GHz 802.11g/b
RF Transceivers with Integrated PA
General Description
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.
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.
