摘要
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.
