Wavelet Lab’s xSDR is a compact, single-sided M.2 2230 software-defined radio (SDR) module crafted for seamless integration into laptops, embedded systems, and edge computing devices. As the successor to the company’s previous uSDR, the “x” in xSDR signifies “extended,” enhancing it with 2×2 MIMO support and a broader frequency range while maintaining its small size.
The module incorporates the Lime Microsystems LMS7002M RFIC and an AMD Artix-7 XC7A50T FPGA, similar to the LimeNET Micro 2.0 Developer Edition board. This setup provides a tuning range from 30 MHz to 3.8 GHz and a sample rate up to 122.88 MSPS, making it ideal for cellular research (LTE/5G), spectrum analysis, satellite tracking, and high-speed data links (with two modules).
