SDR-2104 - 3U SpaceVPX Software-Defined Radio

Overview

SDR-2104 is a software-defined radio with 4 transmit and 4 receive channels in a ruggedized 3U SpaceVPX form factor, supporting RF operation across UHF through X-band.

The system performs RF digitization, waveform generation, and signal processing across multiple channels for communications, sensing, and ranging applications. SDR-2104 is designed for integration into spacecraft payloads requiring multi-channel RF capability and deterministic performance.

Development Kit

The SDR-2104 Development Kit enables engineers to evaluate RF performance, develop custom firmware and waveforms, and enter system integration fully prepared, with fewer surprises and faster progress to flight.

With direct access to RF interfaces, FPGA fabric, and onboard processors, you can rapidly prototype, iterate, and refine mission-specific configurations in a lab setting. A complete board support package (BSP), including boot firmware, device drivers, and example software, removes bring-up friction so your team can focus on building and validating your mission application.
