| Abstract: | An analytical expression for the relationship between gain and noise figure is derived for the design of the microwave broadband low noise transistor amplifier in this paper.The characteristic of analytical solutions is discussed in detail,which simplifies the empirical design method.The microwave low noise HEMT is also analyzed and the results are in agreement with those gained by empirical method. |
| Keywords: | microwave low noise amplifier gain noise figure analytical expression |
