低噪声放大器的ADS设计与仿真

ADS the Design and Simulation of LNA Using ADS

利用ADS仿真软件设计低噪声放大器的方法及主要步骤,使用ADS器件库中的sp模型,重点进行了输入和输出匹配电路的设计.低噪声放大器工作在L波段,噪声系数小于1.8dB,增益大于13dB.通过设计可以看出,利用ADS进行微波电路仿真,可以很方便的得出最佳电路设计,指标完全符合规定值.

The paper discussed a Low Noise Amplifier （LNA） design using the microwave circuit CAD software： Agilent_ADS. In order to simply design, we used sp_model of ADS device library. The main emphasis will be put on input and output circuit design and the parameters of the LNA will include the following： Operating frequency 2GHz, Noise Figure 〈 1.8 dB, Gain 〉 13 dB. Advanced Design System （ADS） soft ware is used to simulate the results of design instance and the result shows that the performance well answers for the previous target.
