 In News

Callisto offers Cryogenic LNA which is cooled at cryogenic temperature to improve the Noise Temperature (NT). The compact cryogenic LNA is suitable for remote location with hard weather conditions. This product allows high reliability, better maintainability, high RF performance (gain > 50dB and NT < 50K), reasonable cost, small size and weight, and allows to cope with the higher payload downlink data rate for planned Earth Observation missions for example. The estimation of the MTBF is more than 90,000 hours. That means no maintenance is required with this system for about 10 years. Moreover, the power consumption is low compared to standard cryogenic systems, about 200W. Please see the following link for more details on the Compact Cryo LNA.
