| Abstract: | During the process of designing LNA,the design of matching networks plays a great important role because it affects the performance of the amplifier dramatically.At first the stability,noise figure and power gain of the low noise amplifier are analyzed.Then a design approach using Ansoft Designer is analyzed,which is a general purpose CAD package for performing high frequency circuits.Some tips for the improvement of the LNA performance are discussed.By using this approach,the design period can be reduced and better performance is obtained. |
