EWC 27 HDR-TM X Band Transmitter

X-band transmitter can transmit up to 13.3 GB per pass with a 5 m station, designed for LEO CubeSat & Nanosatellites

SYRLINKS EWC27 X Band transmitter has been designed to meet a new increasing market among industries and universities in the field of CubeSat and Nanosatellites, especially for Low Earth Orbit (LEO), around 500/800 km above earth.

Due to the small size of these satellites, one of the main challenges is low consuming equipment, especially for radios communication links.

In order to solve this constraint, Syrlinks (with CNES support) has developed a high performance, high data rate, high efficiency, power amplifier, and small size transmitter in X-band (8GHz) for telemetry downloading on NanoSat and CubeSat platforms.

The use of an X band transmitter significantly increases the downlink capacity of the payload telemetry subsystem. With a bit rate commutation operated in time splitting or versus predicted Eb/N0 during a pass, up to 13.3 GB per pass can be downloaded on a 5 m station or 5,8 GB per pass on a 3,4 m station.
