Abstract :
An alternative LNA design flow that addresses some of the typical issues connected with MMIC realisation is given in this contribution. The role of the input matching network is highlighted and investigated for low noise applications. Following the proposed design flow, an LNA test vehicle has been realised. The LNA´s noise figure is less than 0.55 dB while its associated gain is better than 35 dB on the whole C-Band (4-8 GHz).
