Dual-Band Modem IC (PHY) for WLAN System Solutions

The PMB 8787 provides the complete modem functionality for a dual-band wireless LAN chipset.

It contains the signal processing functionality for both the DSSS/CCK and the OFDM modulation/demodulation needed for an 802.11a/b/g compliant system.

The PMB 8787 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 8789 MAC IC.

The device is fabricated in an advanced 0.13 µm CMOS-technology and will be available in a LFBGA-81 package.
