Abstract
This paper relates the state of the art of the HEMT low noise technologies for the space applications at millimeter wave and specially for the earth observation in the G-band (140 – 220 GHz)).The different III-V technologies (HEMT and LNA)and their associated performance are presented.Parameters limiting the improvement of high frequency characteristics for HEMTs with the downscaling process are studied.
