Celestia Callisto is proud to announce the development of its new Ka-band (25.5-27 GHz) Ambiant LNA. The only wave-guide input / coaxial output Ka-band currently on the market, Callisto embarked upon a total redesign in order to improve on our already high-performing product.

Our MKII Compact is a smaller, self-contained Cryogenic LNA that really packs a punch! Equipped with a Stirling cooler manufactured by Sunpower, Inc, the Compact can house up to 2 RF chains in a (much) smaller model.

Callisto is pleased to announce that it has been awarded a contract by Safran Data Systems to supply 12 Low Noise Amplifiers (LNA) operating in the 25.5 to 27 GHz Band.

Callisto has supplied 2 units of Compact Cryo Low Noise Amplifiers (LNAs) in K-Band (20GHz) for the North American market.

As part of the R & T plan for the year 2018 (TC7 technical axis), Callisto is developing for the CNES a Q-band LNA module dedicated to ground station.

Callisto has launched a breakthrough lower cost “Compact” cryo-LNA version using a zero-maintenance cryo-cooler. The product has a proven track record in Space Communications and Radioastronomy/VLBI applications, with several units produced for ESA, CNES and Zodiac Data Systems (ZDS).

Callisto is pleased to announce improved noise temperature (NT) specifications for the 26 GHz Compact Ultra-Low Noise Amplifier. Due to the introduction of latest state-of-the art Indium Phosphide HEMT technology we are able to offer Noise Temperature < 35K (0.5dB). Previous specification 50K.

Callisto is pleased to announce that it has been awarded a contract by the Bundesamt für Kartographie und Geodäsie to supply QRFH Ultra Cryogenic Receiver for VLBI (Very Long Baseline Interferometry) application. BKG is responsible in Germany as a federal office for tographical basic data, cartography and geodesic reference systems.

We are very happy to announce a successful FAT for our most recent project with Bundesamt für Kartographie und Geodäsie (BKG) to equip one of their antennas at the Wettzell site.

Callisto is pleased to announce that an important milestone has been passed at the end of 2015 for its new “Compact”, zero maintenance cryogenic receiver including the Caltech designed QRFH feed: the first light on a VLBI telescope!
