摘要
首先简要介绍微波低噪声放大器的设计理论和方法，然后介绍使用Agilent公司的微波电路CAD软件ADS进行仿真和优化设计一个X频段的低噪声放大器的方法和过程。对制成品的实际测试和调试表明，此放大器达到了预定的技术指标，性能良好。其工作频段为8．6—9．5GHz，噪声系数≤1．8dB，增益为23dB，带内平坦度≤±0．5dB。
The design theory and method of a microwave low noise amplifier （LNA） is introduced. Then, the technique and process of simulating and optimizing an X band LNA with ADS software by Agilent is explained. Finally, the practical test and debugging of the product demonstrate that this LNA meets the technical requirements and works well. Its operation band is =23 dB, in-band flatness≤0.5 dB. 8.6 - 9.5 GHz, noise figure （NF） ≤ 1.8 dB, gain
