Abstract

Radioastronomical observation development pushes technology research to develop equipment working up to 100-150 GHz. This trend makes the noise contribution of the low noise amplifiers (LNA) more serious. A significant improvement comes from the use of indium phosphide (InP) technology, as it gives the best noise performance in this range. Moreover, as radioastronomy is moving towards the array receiver configuration, this implies high integration and repeatability. In the frame of the FARADAY Project, we have been involved in designing several kinds of MMIC amplifiers in the 18-26 GHz range in order to approach the InP technology and the MMIC design methodology.
