摘要

研制了一种用于k波段通信系统的高效率放大器。在17至21 GHz的频率范围内，三级放大器的平均增益为28 dB。在19.5 GHz频率下，6伏运行的放大器以45%的功率附加效率获得28 dBm的输出功率。这是迄今为止报道的采用标准生产pHEMT工艺制造的高增益3级放大器的最高功率附加效率。此外，放大器采用高度紧凑的布局，仅使用3mm /sup / GaAs面积，从而最大限度地降低了通信系统中的芯片成本。

High efficiency K-band amplifier for on-satellite wireless communication systems

A high efficiency amplifier has been developed for use in K-band communication systems. The 3-stage amplifier achieves an average gain of 28 dB over the frequency range of 17 to 21 GHz. Six volt operation of the amplifier attains 28 dBm of output power at 45% power added efficiency at 19.5 GHz. This is the highest power added efficiency reported to date for a high gain, 3-stage amplifier fabricated with standard production pHEMT processing. Additionally, the amplifier utilizes a highly compact layout using only 3 mm/sup 2/ of GaAs area, which minimizes chip cost in communication systems.
