摘要

低噪声放大器(LNA)的目的是将接收到的信号放大到可接受的水平，同时将噪声降到最低。LNA在通信系统中用于放大由天线捕获的非常微弱的信号。微波电路中LNA的设计需要权衡或仔细平衡许多重要参数，如增益、噪声系数(NF)和稳定性。鉴于此，有必要作出计算选择，以实现最优功能的LNA。本文提出了一种基于集总元件(离散无源元件)的单级2.0 GHz LNA输入输出匹配网络优化设计方法。用于本设计的射频(RF)晶体管是ATF-21170，通过其散射(S)参数进行建模。这是一种高性能、低噪声的砷化镓肖特基势垒闸场效应晶体管。LNA的设计使用传统技术来增强1.8GHz到2.6GHz频率范围内的微弱蜂窝信号。该设计是借助先进设计系统(ADS) 2020软件完成的。成功设计了工作频率为2.0GHz的LNA，增益为14dB，最小噪声系数(NFmin)为0.83dB。

Design of An Optimal Low Noise Amplifier (LNA) for Signal Boosting

The purpose of a Low Noise Amplifier (LNA) is to amplify received signals to acceptable levels while minimizing noise. The LNA is used in communication systems to amplify very weak signals captured by an antenna. The design of an LNA in Microwave circuits requires a trade-off or careful balance of many important parameters such as Gain, Noise Figure (NF), and Stability. In view of this, it is essential to make calculated choices to realize an optimally functioning LNA. This paper presents a single stage 2.0 GHz LNA optimal design using lumped elements (discrete passive components) for the input and output matching networks. The Radio Frequency (RF) transistor used for this design is the ATF-21170, which is modelled by its Scattering (S) parameters. This is a high performance, low noise Gallium Arsenide Schottky barrier-gate Field Effect Transistor. The LNA is designed using conventional techniques to boost weak cell signals in the frequency range of 1.8GHz to 2.6GHz. The design is done with the aid of Advanced Design System (ADS) 2020 software. The LNA was successfully designed at an operating frequency of 2.0GHz with a gain of 14dB and a minimum noise figure (NFmin) of 0.83dB.

期刊介绍： Remote Sensing Information is a bimonthly academic journal supervised by the Ministry of Natural Resources of the People's Republic of China and sponsored by China Academy of Surveying and Mapping Science. Since its inception in 1986, it has been one of the authoritative journals in the field of remote sensing in China.In 2014, it was recognised as one of the first batch of national academic journals, and was awarded the honours of Core Journals of China Science Citation Database, Chinese Core Journals, and Core Journals of Science and Technology of China. The journal won the Excellence Award (First Prize) of the National Excellent Surveying, Mapping and Geographic Information Journal Award in 2011 and 2017 respectively. Remote Sensing Information is dedicated to reporting the cutting-edge theoretical and applied results of remote sensing science and technology, promoting academic exchanges at home and abroad, and promoting the application of remote sensing science and technology and industrial development. The journal adheres to the principles of openness, fairness and professionalism, abides by the anonymous review system of peer experts, and has good social credibility. The main columns include Review, Theoretical Research, Innovative Applications, Special Reports, International News, Famous Experts' Forum, Geographic National Condition Monitoring, etc., covering various fields such as surveying and mapping, forestry, agriculture, geology, meteorology, ocean, environment, national defence and so on. Remote Sensing Information aims to provide a high-level academic exchange platform for experts and scholars in the field of remote sensing at home and abroad, to enhance academic influence, and to play a role in promoting and supporting the protection of natural resources, green technology innovation, and the construction of ecological civilisation.
