K波段宽带低噪声放大器的设计
esign of K Band Broadband Low Noise Amplifier
使用宽带匹配理论设计一种用于K波段的宽带低噪声放大器。放大器采用NEC公司的NE350184C晶体管，通过分支线进行输入输出匹配，利用ADS软件进行设计、优化和仿真，放大器输入输出端口采用波导—微带转换进行过渡。最后设计出在19GHz—23GHz频率范围内增益大于12dB，噪声系数小于1.5dB的宽带低噪声放大器。
In this paper, a low noise, wide band amplifier for k band is presented, which used the NE350184C transistor of NEC Company. The input and output matching circuit is designed by branch lines. The design, optimization and simulation are completed by ADS. Waveguide-to-microstrip transitions are added to the input and output ports. At last, the characteristic of the LNA is frequency: 19GHz-23GHz; gain > 12dB; gain flatness < 1dB; noise figure<1.5dB.
