The Cubecom HDRTX X-band Gigabit Transmitter is a configurable, multi-channel X-band transmitter with two independent transmission paths. Each channel has a symbol rate of up to 100 Msps.

The system implements DVB-S2 encoding and is suitable for missions that generate large volumes of data, such as multispectral imagers.

Channel bonding is included in order to combine multiple channels to constitute larger transmission bandwidths.

The HDRTX X-band Gigabit Transmitter enables the downlinking of data in a single satellite pass and adaptive modulation and coding optimizes throughput.
