Callisto at EuMW in Madrid 2018

Published by

After its attendance at ISD ESTEC in Noordwijk on the last 11 & 12th of September, Callisto is continuing its European tour with its participation in European Microwave Week, which provides access to the very latest products, research and initiatives in the microwave sector, on the 25 & 26th September, booth 248, in Madrid, Spain.

On that event Callisto is going to present its cryo feed system project carried out with the partnership of the University of Cantabria Wednesday 25th of September between 5.10 and 5.30 PM.

This paper describes the design of a ground station antenna feed system, that includes feed horn, polarizer, rejection filter, mono-pulse tracking coupler and low noise amplifiers with polarisation switching. The entire feed system assembly is cooled to cryogenic temperature (T < 10 K) in order to maximise the G/T of the ground station antenna (3dB/K gained). The cryogenic cooling system described is fully redundant and this novel design allows one cryocooler to be removed and replaced, while the other cryocooler is still running. The design has been submitted for patent protection.
