In wireless mobile communications and wireless local area networks (WLAN),advanced InGaP HBT with power amplifiers are key components.In this paper,the microwave large signal dynamic waveform characteristics of an advanced InGaP HBT are investigated experimentally for 5.8 GHz power amplifier applications.The microwave large signal waveform distortions at various input power levels,especially at large signal level,are investigated and the reasons are analyzed.The output power saturation is also explained.These analyses will be useful for power amplifier designs.
