Abstract :
In this paper, a SiGe BiCMOS power amplifier has been designed, showing the competitive performance compared to GaAs HBT. The 2.4 GHz power amplifier realized in IBM 0.35 mum SiGe BiCMOS technology. As shown in Fig.5, under high power mode, the measured gain is 24 dB and the input return loss Sn is better than -15 dB, the output return loss S22 is ~9.6 dB at 2.45 GHz. The PA exhibits PidB of 24.1 dBm with the peak power added efficiency of 35.1% (Fig.6) at 2.4 GHz range. The second and third harmonics are measured to be -40.2 dBc and - 51.2 dBc respectively.
