EWC27 – X-Band Transmitter

The EWC27 X-Band Transmitter addresses the challenge of low power consumption in small satellites, providing high data rate telemetry up to 100 Mbps (optional) and robust transmission in the X-band (8GHz). It incorporates a smart concept for controlling power amplifier supplies to optimize efficiency for each RF power level, ensuring power consumption is always optimized. The power supply architecture is designed to protect the transmitter against latch-up effects caused by heavy ions in space. Syrlinks’ ‘nano’ radios, including the EWC27, are designed for 2-year lifetime LEO missions, leveraging Syrlinks’ experience from the ROSETTA mission in designing and manufacturing radios for micro and mini satellites. The product quality approach has been refined since the MYRIADE platform and ROSETTA mission with CNES. The EWC27’s design and manufacturing primarily rely on qualified COTS components, with stressing tests performed on QM units. Its architecture inherits from the EWC28 X-Band transmitter, which is already in-flight proven on various missions, notably PROBA-V (ESA/QinetiQ Space nv). The EWC27 XBT can be adapted for Deep Space applications, particularly in terms of frequency band and bitrate. The SME label awarded by CNES highlights Syrlinks’ excellence as a key space supplier.
