General Desc ription
The MAX2822 single-chip transceiver is designed for
802.11b (11Mbps) applications operating in the 2.4GHz
to 2.5GHz ISM band. The transceiver includes all the
circuitry required to implement an 802.11b RF-to-base-
band transceiver solution, including the power amplifi-
er, transmit/receive switch, and 50
matching. The fully
integrated receive path, transmit path, VCO, frequency
synthesis, and baseband/control interface provide all
the required active RF circuitry. Only a small number of
passive components are needed to form the complete
radio front-end solution.
The IC eliminates the need for external IF SAW and RF
image-reject filters by utilizing a direct-conversion radio
architecture and monolithic baseband filters for both
receiver and transmitter. It is specifically optimized for
802.11b (11Mbps CCK) and 22Mbps PBCC applica-
tions. The baseband filtering and Rx and Tx signal
paths support the CCK modulation scheme for BER =
10
-5
at the required sensitivity levels.
The transceiver is suitable for the full range of 802.11b
data rates (1Mbps, 2Mbps, 5.5Mbps, and 11Mbps) as
well as the higher-rate 22Mbps PBCC standard. The
MAX2822 is available in the very small 7mm x 7mm 48-
lead QFN or thin QFN packages. The small solution size
makes it ideal for small form-factor 802.11b applications
such as PDAs, SmartPhones, and embedded modules.
