| Abstract: | The technique and process of simulating and optimizing an X band low noise amplifier with ADS software by Agilent company is introduced. The product was tested and debugged when the operation band is 8.6~9.5 GHz, noise figure (NF) is 1.8 dB, gain is 23 dB, and in band flatness is 0.5 dB. The results indicate that this low noise amplifier meets the technical requirements and works well. |
