Product Details
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 applications. 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.

Description
The MAX2822 evaluation kit (EV kit) simplifies testing of the MAX2822. The EV kit provides 50Ω SMA connectors for all RF and baseband inputs and outputs. Differential-to- single-ended and single-ended-to-differential line drivers are provided to convert the differential I/Q baseband inputs and outputs to single ended.
The EV kits simplify evaluation of the MAX2822's receive and transmit performance in 802.11b applications operating in the 2.4GHz to 2.5GHz ISM band.
