NTRODUCTION

The WMG623A is a Wi-Fi PCI Express Card that allows simple design-in

802.11b/g/n Wi-Fi functionality for various products, such as notebooks

and home gateways.

The WMG623A includes a built-in high-performance CPU that off-loads Wi-
Fi packet processing tasks from the main processor. The hardware form

factor follows the PCI Express standard, but the data path conforms to an

RGMII interface. The result is a card that delivers a higher data transmit

rate than conventional mini-PCI modules.

The WMG623A is compliant with IEEE 802.11n standard and operates in

the 2.4 GHz frequency band. The card’s MIMO antenna architecture is 2T3R

(two transmit, three receive), which supports up to 450 Mbps throughput

rate. The card also supports 20 MHz and 40 MHz bandwidth channels, as

specified in the 802.11n standard.
