A high-performance, compact, software-defined radio designed to operate in LEO and airborne environments, SDR-1001 is suitable for demanding RF, digital signal processing, and communications applications supporting custom waveform development or DVB-S2/DVB-S2X and CCSDS modems.

Use as a stand-alone radio or combine with other CesiumAstro modules for a complete bits-to-photons solution.

SDR-1001 includes four receive channels, four transmit channels, and a state-of-the-art FPGA in a credit-card-sized footprint.

Low-profile and compact 50 mm x 84 mm x 13 mm packaged form-factor. Thermal pillars bring heat to the flat surface.
