摘要
Abstract
To reduce the noise of receiving front-ends, the design and fabrication of an ultra-wide band Low Noise Amplifier(LNA), were presented based on negative feedback and wide band matching technologies. The amplifier tube ATF-54143 made by Avago was chosen for this design, whose key indexes were simulated and optimized by using ADS2009. The test results indicate that the gain is greater than 24 dB;the flatness is lower than ± 2 dB over the four octaves 0.2 GHz-3.2 GHz. Noise Figure(NF) is below 1.2 dB over 0.2 GHz-2 GHz; and less than 1.5 dB over 2 GHz-2.6 GHz; less than 2 dB over 2.6 GHz-3.2 GHz.The good performance of this amplifier satisfies the requirement of engineering application, and it can be applied to the receiver front-end of communication systems.关键词
