The PMB 8680 is a low power, high performance dual-band RF Transceiver for IEEE Wireless LAN Standards 802.11a, 11b and 11g.
The PMB 8680 is designed to form an Infineon WLAN chipset in combination with the PMB 8787 Baseband PHY IC, the PMB 8825 dual-band Power Amplifier and the PMB 8789 MAC IC.
This highly integrated solution together with low external component requirement (low Bill of Material) shortens time to market.
