摘　　要：介绍使用Agilent公司的微波电路CAD进行仿真和优化设计L波段低噪声放大器的方法和过程,并对制成品在工作频段为1.7～1.9 GHz,噪声系数0.9 dB,增益为22 dB,带内平坦度0.5 dB进行实际测试和调试,结果表明,此放大器基本达到预定的技术指标,并对放大器低温测试结果进行探讨。The technique and process of simulation and optimizing an L band low noise amplifier with ADS software by Agilent company is instroduced. The product was tested and debuggged when the operation band is 1.7--1.9 GHz,noise figure （NF） is 0. 9 dB,gain is 22 dB, and in-band flatness is 0. 5 dB. The results indicate that this low noise amplifier meets the technical requirements basically ,and it is analysed that the results of the amplifier in low temperature.
