Dual-Band Power Amplifier for
WLAN Systems
The Infineon dual-band Power Amplifier PMB 8825
is an extremely linear, high power SiGe amplifier
for Wireless LAN applications and is fully compli-
ant with IEEE802.11a, 11b and 11g standards with
data rates up to 54 Mbit/s in 802.11a and 11g mode.
The PMB 8825 is designed to form an Infineon
WLAN chipset in combination with the PMB 8680
dual-band RF Transceiver, the PMB 8787 dual-band
Modem IC (PHY) and the PMB 8789 MAC IC.
