Abstract :
Historically radio telescope have mostly consisted of large dishes with a single feed system at the focus. Recently there has been a trend towards multi-beam systems to make more efficient radio maps of the sky. Three teams, funded under the EU FARADAY project, have designed receiver arrays developed using the lattice-matched indium phosphide foundry process of NGC, California. Receiver architecture and measured results are described
