Two new X Band compact cryogenic low noise amplifiers for the CNES

Callisto is please to announce the award of a new contract by the CNES.  The contract is concerned with the supply in October 2008 of two compact X band (8.0-8.5GHz) cryogenic low noise amplifiers (LNAs) for STEREO satellite ground station .

Callisto has many years experience producing very low noise cryogenic amplifiers for ESA satellite ground stations. The first generation products were aimed at ultimate low noise performance, which is required for Deep Space satellite missions.

Callisto are now able to offer compact cryogenic low noise amplifiers,  which can be used in the wider field of satellite communications, particularly in the remote sensing band of 8.0 to 8.4 GHz. The benefit of using a cryogenic LNA, in system terms, is that a smaller diameter antenna can be used to achieve the required G/T performance compared to a system with a conventional un-cooled LNA.

The STEREO project is the third mission of the international scientific program of the study of the relationship Sun-Earth STP (Solar Terrestrial Probes Program). It is a set of two satellites from NASA with instruments designed and produced by American and European scientists. The purpose of the STEREO mission is to provide original information on solar flares and their effects on terrestrial environment. A network of ground stations, set up by NOAA, receives STEREO data continuously. A CNES antenna in Aussagel ( near to Toulouse), has been upgraded for this occasion and completes this first "space weather" world network.
