摘要: 介绍与实现了一种X波段宽带低噪声放大器(LNA)。该放大器选用NEC公司的低噪声放大管NE3210S01(HJFET),采用微带分支线匹配结构和两级级联的方式。利用ADS软件进行设计、优化和仿真。最后研制的放大器在10-13GHz范围内增益为(21.5±1)dB,噪声系数小于2 dB,驻波比小于1.8。

Abstract: An X band broadband low noise amplifier (LNA) is presented. This amplifier, using NEC’s HJFET NE3210S01, had a microstrip stub matching structure and a two-stage topology. ADS was used as a tool to design, optimize and simulate. The designed amplifier exhibited broadband operation from 10GHz-13GHz with noise figure less than 2dB, Gain 21.5dB±1dB and SWR less than 1.8.
