SRX‑8 High‑speed X‑band Transmitter
The Satlab SRX‑8 is a DVB‑S2 X‑band transmitter designed for high‑speed data transfer at rates up to 1.4 Gbit/s while weighing just 300 g, making it ideal for downlinking large volumes of payload data from micro- and nano-satellites.
The transmitter operates in the ITU Earth observation X‑band with support for all DVB‑S2 MODCODs, allowing simple integration with commercial ground station providers.
