uSDR — Ultra-Compact Embedded SDR Platform
High-performance M.2 SDR module for embedded RF systems and edge deployments.
Why uSDR
uSDR is designed for embedded RF systems where size, power, and integration matter. It combines RF front-end, FPGA processing, and high-speed interfaces in a compact M.2 form factor — enabling direct integration into compute platforms, edge devices, and custom hardware.
Key capabilities
Cellular communication
Remote SDR operation and data streaming via WebSDR platform or custom transport layers.
Temperature stability
LMS6002D BiCMOS RFIC delivers predictable RF performance across −50 °C to +100 °C chip temperature.
Embedded form factor
M.2 2230 A+E key · USB 2.0 · PCIe 2.0 ×2 card for compact, high-performance frequency analysis devices.
Worldwide data link
Build point-to-point communication channels via the wsdr.io web platform.
System architecture
LMS6002D RFIC handles 250 MHz – 3.8 GHz RX/TX, paired with an LTC5562 up-converter and a 7th-order 250 MHz LPF for the dedicated 1–250 MHz RX-only band. An AMD Artix-7 (XC7A35T / XC7A50T) FPGA performs framing, decimation and DDC/DUC, exposing the host via M.2 2230 A+E key · USB 2.0 · PCIe 2.0 ×2.
