Wavelet Lab's micro-SDR lineup is expanding beyond uSDR with two new embedded SDR platforms: xSDR and sSDR.
Both products continue the same design direction that shaped uSDR: compact hardware, embedded-first integration, browser-accessible workflows, open software support, and a focus on making advanced RF systems easier to deploy.
xSDR extends the uSDR concept into a more capable 2×2 MIMO M.2 radio. sSDR takes the platform further with wide frequency coverage up to 11 GHz, higher-speed PCIe connectivity, and an UltraScale+ FPGA architecture for more demanding signal-processing workloads.
Together, xSDR and sSDR give developers a wider set of options for RF research, telecom prototyping, embedded wireless systems, signal intelligence , and advanced SDR development.
| Platforms | Frequency Range | Channels | Form Factor | Best For |
|---|---|---|---|---|
| uSDR | up to 3.8 GHz | 1 RX / 1 TX | M.2 | Compact SDR, WebSDR, education, portable RF experiments |
| xSDR | 30 MHz–3.8 GHz | 2 RX / 2 TX | M.2 2230 A+E key · USB 2.0 · PCIe 2.0 ×2 | Embedded RF, MIMO, telecom prototyping, wireless research |
| sSDR | 30 MHz–11 GHz | 2 RX / 2 TX | M.2 M-key | X-band, wideband RF, advanced DSP, signal intelligence |
xSDR: extended M.2 SDR for embedded RF systems
xSDR is designed as a compact, single-sided M.2 software-defined radio for modern embedded platforms. The "x" stands for extended: extended RF capability, extended bandwidth, and multi-channel operation while keeping the small M.2 form factor that made uSDR practical for laptops, SBCs, tablets, and embedded systems.
Key xSDR capabilities include:
- 2×2 MIMO RX/TX channels
- 30 MHz to 3.8 GHz tuning range
- up to 122.88 MSPS sampling
- M.2 2230 A+E key · USB 2.0 · PCIe 2.0 ×2 form factor
- compatibility with existing uSDR adapters
- support for embedded RF, wireless research, rapid prototyping, and signal intelligence applications
This makes xSDR a practical platform for developers who need more channels and higher performance than uSDR while still keeping the hardware compact and easy to integrate.
sSDR: wideband M.2 SDR up to 11 GHz
sSDR is designed for users who need higher frequency coverage and more processing headroom. It expands the Wavelet Lab M.2 SDR family into wideband applications with coverage from 30 MHz to 11 GHz.
Key sSDR capabilities include:
- 2×2 MIMO RX/TX channels
- 30 MHz to 11 GHz tuning range
- up to 122.88 MSPS sampling
- AMD Artix UltraScale+ XCAU7P FPGA
- PCIe 3.0 x4 host interface
- M.2 M-key form factor
- support for advanced RF, X-band, radar, instrumentation, and signal intelligence workflows
Operating near 10.5 GHz places sSDR in an important RF region used for radar, remote sensing, communications, instrumentation, and advanced radio-location systems.
A scalable SDR product family
With uSDR, xSDR, and sSDR, Wavelet Lab is building a scalable embedded SDR family.
uSDR remains the compact entry point for browser-based SDR workflows, education, spectrum analysis, and portable RF experimentation.
xSDR adds 2×2 MIMO operation and expanded performance for embedded RF development, LTE/5G experimentation, spectrum analysis, and multi-channel research.
sSDR extends the product family into higher-frequency and higher-bandwidth applications, including X-band experimentation, advanced RF sensing, and acceleration-ready signal processing.
Built for software and platform continuity
The hardware roadmap is only one part of the story. Wavelet Lab's SDR devices are designed to integrate with existing SDR ecosystems such as GNU Radio, SoapySDR, and srsRAN, while also supporting browser-based workflows through WebSDR.
This gives users two paths:
- native SDR workflows for maximum compatibility and performance
- WebSDR workflows for browser-based control, visualization, DSP prototyping, and remote operation
This combination makes the platform useful for both traditional SDR users and teams looking for more modern web-native RF development tools.
Applications
xSDR and sSDR are suitable for:
- embedded RF systems
- wireless research
- private cellular prototyping
- LTE and 5G experimentation
- spectrum monitoring
- signal intelligence
- radar and X-band research
- RF education and training
- multi-channel receiver and transmitter development
- edge RF systems
What comes next
The launch of xSDR and sSDR marks a broader direction for Wavelet Lab: compact SDR modules that scale from simple browser-based experiments to multi-channel, wideband, and high-frequency RF systems.
As the product family grows, Wavelet Lab will continue to focus on compact hardware, open software compatibility, browser-based tools, and practical integration into real-world RF systems.
