Abstract

A Ku-band 60W GaN power amplifier is presented. To obtain the high efficiency, new matching circuit topology to control the reflection phase at the 2nd harmonic frequency (2fo) is applied to the power amplifier. The measured power added efficiency (PAE) of 44.9% with the output power of 47.9dBm (62.2W) is obtained in the 15GHz-band. To the best of our knowledge, the PAE is the highest of the Ku-band GaN power amplifiers reported to date.

功率增加效率45%，ku波段60W GaN功率放大器

介绍了一种ku波段60W GaN功率放大器。为了获得高效率，在功率放大器中应用了新的匹配电路拓扑来控制2次谐波(2fo)的反射相位。在15ghz频段测量到的功率附加效率(PAE)为44.9%，输出功率为47.9dBm (62.2W)。据我们所知，PAE是迄今为止报道的ku波段GaN功率放大器中最高的。
