Abstract :
This paper presents a highly linear 5-GHz band power amplifier IC with integrated novel CMOS active bias circuit in SiGe BiCMOS technology for wireless LAN applications. The power amplifier IC consists of three-stage amplifier, the CMOS active bias circuit for linearizing SiGe HBT and all matching circuits. The power amplifier IC has exhibited a measured output power of 17.0 dBm, an EVM of 0.9 % and a dc current consumption of 284 mA under 54 Mbps OFDM signal at 5.4 GHz.
