The objective of the activity is to design, develop and test an enabling inter satellite link V- Band solid state power amplifier module breadboard delivering 10W saturated power with better than 15% efficiency for Intersatellite RF links of at least 10Gbps over a distance of 1000 km.
Targeted Improvements:Enabling technology development for RF Intersatellite links achieving 10Gbps and beyond in the 1000 km distance range.
Description:Future NGSO constellations, GSO relay satellites relay and also multiple access telecom reconfigurable satellite systems require high data-rate inter-satellite-links (ISL) to overcome feeder link capacity saturation.RF ISL have been demonstrated more than 20 years ago and current ISL achieve 1-2 Gb/s per channel. Higher data rates are achieved with optical ISL such as on EDRS with up to 1.8Gb/s over long distances and 5.625Gb/s over short distances. An alternative or complementary solution is RF data links using a very high frequency band where significant bandwidth is available (59 to 71 GHz). More than10Gb/s is feasible for distances of up to at least 5000km and even higher data rates for short distances.
In order to enable RF ISLat10 Gb/s and above, this activity will design and develop the critical technology: a V-Band solid state high power amplifier (SSPA) module. A concept for the RF output section of the ISL shall be selected and a breadboard of a 10 W V-Band SSPA module shall be manufactured and tested with a power added efficiency of at least 15%.
