The Cubecom XTX X-band Transmitter is a compact, flight-proven nanosatellite X-band transmitter with a Cubesat Kit PC/104 form factor.

The transmitter implements the DVB-S2 standard up to MODCOD 21 which supports QPSK, 8PSK, and 16APSK modulation at a symbol rate of 25 Msps.

The use of the DVB-S2 standard (concatenated encoding optional) enables compatibility with commercial-of-the-shelf (COTS) satellite demodulators.

The XTX X-band Transmitter also has a maximum encoded data rate of 100 Mbps, making it suitable for space applications that require a high data rate downlink.
