EWC30 X-Band Transmitter
EWC30 CLASS 3 (& CLASS 2) is a reliable, high performance & low power consumption X Band (8GHz) Transmitter, which was developed by CNES (French Space Agency) and Syrlinks for downloading telemetry on small platforms.
Since 2014, Syrlinks offers a 2nd generation of X Band (8GHz) transmitter, named EWC30, based on space qualified components and fully compliant to ECSS-Q-ST-60C Class 3 standard. EWC30 series operates in the 8025–8400MHz frequency range and exhibits a data rate up to 400Mbps.
Evolutions of the equipment are currently under development to allow data rates higher than 400Mbits/s, for instance 600Mbits/s using 8PSK and high order modulation schemes.
The transmitter includes a DC-DC converter having a galvanic isolation.
Two versions are available: (1) One low power 3dBm for using external PA. (2) One high power which can be adjusted at manufacturing from 30 to 40dBm.
For information, Syrlinks CLASS 3 series (EWC29 and EWC30) have been already awarded and commissioned for spacecraft platforms (such as MYRIADE EVOLUTIONS, from CNES/Airbus D&S/Thales Alenia Space), and other missions.
