General Description
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.
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.
