A miniaturized transmitter designed for LEO CubeSat and Small Satellites for Earth Observation / Exploration data downlink applications. With a volume of < 0.5 U and a mass of < 500 g the transmitter operates in Ka-band from 25.5 to 27 GHz and it can reach up to 4 Gbps in transmission making it unique in size and performance ratio.
The transmitter is compliant with DVB-S2X with ACM and up to 256 APSK that makes it compatible with all the most common commercial ground station segments. It is equipped with RADIOSAT SDR that allows to customize its protocols and waveforms up to 1 GHz instantaneous bandwidth.
