Abstract :
This paper presents the results of G-Band Monolithic Microwave Integrated Circuits (MMIC) for passive imaging applications. The studied system is a Y-shaped interferometer. This kind of system provides both high resolution and a compact system. MMIC were made using a 70 nm GaAs metamorphic High Electron Mobility Transistor process from OMMIC (France). A Low-Noise Amplifier performances are presented, measurement results provide a noise figure of 5 dB with a gain of 20 dB on 10 GHz bandwidth around 140 GHz. The second circuit is an oscillator, measurement results give an oscillation frequency close to 146 GHz.
