| Abstract: | To improve SNR in communication system,circuit selection for low noise amplifier is firstly analyzed and components selection methods are determined.Then the design idea of low power amplifier is given.Based on that,the use of ADS software for design of X-band LNA is introduced.Fujits FH13X and Transcom TC1201 chip are adopted with two-stage cascade scheme.The circuit is simulated and optimized to determine the amplifier stability.The final circuit design is obtained after correction with software.Finally,c... |
