At the end of 2014 Callisto has delivered three additional X Band Compact maintenance free cryo LNAs.
These LNAs have 18K of Noise temperature between 8 and 8.5GHz.

Images and Science already returned by the orbiter and the Philae lander are amazing!
The team at Callisto is very proud to be part of this European venture with the cryogenic Low Noise Amplifiers (LNA) designed by Callisto and installed in ESA Deep Space Stations around the world.
Callisto is pleased to announce that the design activities have started for the prototype of a new compact, zero maintenance cryogenic Receiver including the Caltech designed QRFH feed. This new RF receiver is being developed to meet the VGOS specification for VLBI. It could also be used for more general radioastronomy applications.
Steve Rawson, CEO of Callisto gave a presentation on the 1st of July during the Toulouse Space Show on behalf of Invest in Toulouse. He presented the advantages for Callisto to do business in the area of Toulouse since 2011 the date that Callisto moved to Villefranche de Lauragais.
Callisto will be attending the 4th Toulouse Space Show, important international gathering for space stakeholders, from 30th of June to 2nd July 2014 at the Centre de Congrès Pierre Baudis.
Benoît Fauroux, Business Unit Manager together with other staff members are looking forward to meeting you at our stand C28, where some of Callisto's product range will be on display.
We will be happy to share our experience and show our products and applications.
Take advantage of the show to see our new line of products, join us at the Toulouse Space Show....
In the same year as we celebrated our 20th anniversary, Callisto also celebrated the delivery of our 50th and 51st cryogenic system. In December 2013 we completed an order to Zodiac Data Systems for two X-band compact cryo LNAs destined for Earth Observation ground stations. Since 1997 Callisto has delivered over 50 cryogenic systems using both G-M and Stirling coolers.
Callisto has started a project to develop Ka band LNAs for Earth Observation applications.
This project will cover the development of pre-production units for:
- Conventional ambient temperature LNAs
- Compact cryogenic LNAs with 2 reception channels.
The RF band between 25.5 and 27 GHz has recently been designated for downlink of data from Earth Observation and Scientific Research spacecraft. This frequency band has just been assigned for satellite use and future satellites will operate in the frequency to reach very high data rate. Moreover, there are fewer component options compared to more commonly used frequency bands. The aim of Callisto is to develop 26GHz LNA with state-of-the-market performance and also to provide a European source for this kind of LNA.
This project is supported by ESA under a GSTP funding programme.
The ESA station maintenance team of Deep Space Antenna 3 (Malargüe, Argentine) has received support from Callisto for the preventive maintenance of the X-Band cryogenicUltra Low Noise Amplifiers (LNAs).
The cryogenic Ultra Low Noise amplifiers are used to amplify the signal coming from ESA spacecraft and will support the forthcoming Gaia mission (launch planned in December 2013).
In addition to the maintenance support, the DSA3 staff have received a training course from Callisto. The course has been well received by the attendees who enjoyed both detailed theoretical and practical lessons on cryogenic LNA systems for their operations and maintenance.
Callisto attended the 6th ESA Workshop on Tracking, Telemetry and Command Systems for Space Applications at ESOC, Darmstadt, between the 10th - 12th September 2013.
Two papers were presented by Callisto staff:
- "Zero Maintenance X-Band Cryogenic Low Noise Amplifier" presented Callisto's second generation compact X-band LNA that offers 20K noise temperature over 8.0 - 8.5GHz and a very attractive 10 years MTBF.
- "Ka-Band Ground Station Low Noise Amplifier Development for Earth Observation Missions" presented the latest progress in the development of 26GHz LNAs working at room and cryogenic temperatures. The ambient LNA based on commercial MMIC is already commercially available with a noise temperature lower than 160K over the frequency range 25.5 - 27GHz.
In addition Callisto was mentioned in ESA and CNES presentations:
