Abstract :
A set of monolithic low-noise amplifiers have been designed and realised making use of an advanced industrial GaAs 70 nm metamorphic technology with high indium content. Operating frequencies of the realised amplifiers span from C-to W-band, with resulting performance in line with the requirements of many advanced radioastronomy applications. As an example, 2.7 dB NF from 75 to 90 GHz associated to 25 dB gain and 1.3 typical NF from 30 to 50 GHz with 30 dB gain have been achieved.
