Abstract

A 20 GHz 2-stage MMIC (Monolithic Microwave Integrated Circuits) LNA(Low Noise Amplifiers) has been designed. The pHEMT with gate length of 1.15 um has been used to provide ultra low noise and high gain amplification. Series and Shunt feedback circuits were interted to ensured high stability over frequency range of DC to 60 GHz. The size of designed MMIC LNA is 2285um x 2000um(4.57mm2). The simulated noise figure of MMIC LNA is less than 1.7 dB over frequency range of 20 GHz to 21 GHz.
