EnduroSat's S-band transmitter features high data rates and supports a variety of data interfaces and modulation schemes. The module operates in either commercial (2200 – 2290 MHz) or amateur (2400 – 2450 MHz) frequency band. The commercial band is allocated by the ITU for Space Operation Service (Space-to-Earth), Earth Exploration Satellite Service (EESS, Space-to-Earth) and Space Research Service (Space-to-Earth). The transmitter is designed to work in accordance with the DVB-S2 ETSI EN 302 307 standard. CCSDS is also available.

It has two modes of operation. In Idle mode the internal memory can be accessed to store data and also set all transmission parameters. In Trasmit mode the device sends the data either from the internal memory or from the payload through the LVDS interface to the radio channel. In both modes all tranmission parameters (central frequency, output power, symbol rate) can be changed in real time.

The small overall dimensions of the metallic box combined with the robust HW architecture of the S-Band Transmitter makes it suitable for CubeSat or nanosat LEO missions.

The transmitter is fully compliant with the CubeSat standard.
