Abstract:
LNA design meets different challenges because of its simultaneous requirements like good transistor selection, suitable DC biasing network, high gain, low noise figure, good input-output matching circuits, high linearity and good stability. In this paper we have chosen Avago Technologies ATF-58143. The results for Q-point, DC-Bias, Stability analysis are given using Agilent ADS.
