摘要

介绍了一种适用于ku波段卫星通信接收信道的ku波段低噪声放大器。基于微系统设计原理，建立了小型化LNA。采用两级异质结FET级联结构。在合理选择匹配结构的基础上，增加低通滤波器抑制带外干扰。并利用EDA软件对匹配电路进行优化。结果表明，在12GHz ~ 13GHz工作频率范围内，LNA的噪声系数(NF)小于1.55dB，增益大于24dB，且输入输出匹配良好。

Design of Ku-Band Low Noise Amplifier for Satellite Communication Applications

A Ku-band low noise amplifier (LNA) is presented in this paper, which is suitable for the Ku-band satellite communication receiving channel. The miniaturized LNA is established based on the micro-system design principle. The two-stage hetero-junction FET cascade structure is adopted. Based on a reasonable selection of matching structure, a low-pass filter (LPF) is added to suppress out-of-band interference. And the EDA software is applied to optimize the matching circuit. According to the results, the LNA achieves a noise Figure (NF) less than 1.55dB and a gain greater than 24dB in the working frequency range of 12GHz to 13GHz, meanwhile the input and output are well matched.
