In this paper, an experimental validation about the benefit of the input harmonic manipulation on the performance of a microwave power amplifier is presented. With the support of low-frequency measurements on a 0.5x1000 μm2 GaN HEMT, the importance of synthesizing the correct input waveform at the intrinsic section of the device is highlighted. A class-AB tuned-load amplifier has been considered as a case study.

Abstract
In this paper, an experimental validation about the benefit of the input harmonic manipulation on the performance of a microwave power amplifier is presented. With the support of low-frequency measurements on a 0.5x1000 μm2 GaN HEMT, the importance of synthesizing the correct input waveform at the intrinsic section of the device is highlighted. A class-AB tuned-load amplifier has been considered as a case study.File in questo prodotto:
