XLink-X - X Band Transceiver SDR

XLink-X is an advanced transceiver system (Software Defined Radio – SDR) for X-Band communication links of small satellites in LEO environment. The mechanical dimensions are compatible with both CubeSats and larger satellites. The radio interface and radio protocol were developed according to standard CCSDS protocols.

The device supports very high downlink data rates of up to 200 Mbps. Supported modulation schemes include BPSK, QPSK and higher order modulations with appropriate FEC coding schemes. Adaptive Modulation and Coding (AMC) schemes are applicable to maximize data throughput.

The satellite receiver (uplink) for telecommand purposes is designed for standard CCSDS BPSK with BCH coding and net data rates of 56 kbps minimum. Alternatively, X-Band or S-Band uplink receive frequencies can be used.

The payload data interface is based on CCSDS transfer frames.

A special feature of the XLink-X transceiver is theoptional application of two separate Tx channels. They can be used either for an increase of the transmit power or for redundancy purposes.

Features:

• Fully featured and transparent bidirectional X-Band transceiver (SDR)
• CCSDS compliant for physical and synchronisation layer
• Flight grade tested design
• Compact case and low power consumption
• Low-cost COTS design
• Short delivery time
• Additionally available: Extra flat patch antennas tuneable to customer specific frequencies
