The IQ spacecom XLink-L is an L-Band Transceiver System (SDR) suitable for micro, nano and pico satellites in LEO. The physical dimensions of the system allow it to fit in a 1U CubeSat and standard CCSDS protocols are used to develop the radio interface and radio protocol. The systems are designed to be deliver downlink data rates with high net payload rates.With appropriate FEC encoding schemes, the SDR supports higher order forms of modulation, such as BPSK and QPSK. Data throughput maximization is possible through Adaptive Modulation and Coding (AMC) schemes.

A standard CCSDS BPSK with BCH coding is used in the satellite receiver (uplink) for telecommand purposes of the satellites. Alternative uplink receivers in the X-band and S-band frequencies are available.

A feature of the XLink-L transceiver is the optional use of two separate Tx and Rx channels. These can be used for redundancy purposes as well as connect antennas from opposite sides.
