| Abstract(in English) | We have developed a GaAs FET power amplifier that demonstrates a high power-added efficiency of 68% with 17.1W output power and a 16dB linear gain at 1.5GHz. The developed 17W amplifier also exhibited state of the art low distortion characteristics of less than -21dBc NPR at the 5dB-output power back-off point from 2dB-gain compression point. The results indicated that the absolute value of bias circuit impedunce in the low frequency range influences the distortion characteristics of the amplifier. |
