PRODUCT BRIEF
Dual-Band Media Access Controller
(MAC) for WLAN System Solutions
The PMB 8789 WLAN media access controller is
one chip of the wireless system solution from
Infineon Technologies that addresses the need of
the emerging market for wireless LAN and wireless
home-networking products. Using a plurality of
host interfaces, the PMB 8789 supports the MAC
and data buffer management functions and is fully
compliant with the IEEE802.11a/b and 11g WLAN
standards.
The PMB 8789 is designed to form an Infineon
WLAN chipset in combination with the PMB 8680
dual-band RF Transceiver, the PMB 8825 dual-band
Power Amplifier and the PMB 8787 dual-band
Modem IC (PHY).
