摘　　要：文章介绍了一种空间用Ka频段MHEMT三级MIC低噪声放大器的设计,放大器最小噪声系数为1.5dB,增益为30 dB,回波损耗10 dB。该低噪声放大器成品率高,性能指标优于目前同类商业芯片指标。A Ka band three-stage monolithic microwave integrated circuit （MMIC） low noise amplifier has been devel- oped with metamorphic HEMT technology for space application. The low noise amplifier has achieved 1.5 dB minimum noise figure with 30dB gain, and 10 dB input/output return loss. Large amount of measurements show that the low noise am- plifier has achieved a high yield and better performance than current commercial products.
