Product Description

The complete software suite is fully optimized and supports the following platforms and tools:

• Development Environments: MATLAB 2020A, UHD driver

• SDR Toolchains: GNU Radio, GQRX, URH, Audacity
  Users can immediately operate the device on pre-configured virtual machines or perform local installations using our step-by-step tutorials.

We also integrate support for premium open-source projects including:

• Mobile Communications: SRSLTE (4G/5G open-source protocol stack)

• Aviation Monitoring: GR-AIR-MODES (ADS-B signal decoding)

• Satellite Navigation: GPS-SDR-SIM (GPS signal simulation)
  Complete software packages, installation guides, and quick-start manuals are provided.

Key Features

Portable Design

• Compact size, operable via USB power alone, suitable for field deployment with laptops

Plug-and-Play Connectivity

• USB 3.0 interface (backward compatible with USB 2.0)

• Unlike conventional USRP devices: Eliminates Ethernet/fiber interfaces and associated network configuration complexities

Full-Band Coverage

• RF Range: 70MHz–6GHz (covers most testing scenarios)

• Baseband Sampling Rate: Up to 61 MS/s

• Typical Applications:
  1. FM broadcast transceiving
  2. OFDM modulation/demodulation
  3. 4G base station protocol development

Open-Source Ecosystem

• Native GNU Radio compatibility with extensive library components and examples

• Custom program development via UHD driver middleware (independent of GNU Radio toolchain)

• Deep integration with open-source projects:
  1. GQRX (radio reception)
  2. URH (signal analysis)
  3. OpenBTS (open-source base station)

Best Cost-Performance Ratio

• The most economical model in the USRP series with a large user community:
  1. Hundreds of curated open-source applications on GitHub (e.g., GPS-SDR-SIM, SRSLTE)
  2. Well-documented troubleshooting resources

MIMO Capability

• Fully synchronized 2T2R mode:
  1. Enables MIMO applications
  2. Simultaneous dual-channel RF input processing
  3. Concurrent output of two independent baseband waveforms

Performance Validation

Rigorous testing confirms identical performance to OEM devices. Users are encouraged to conduct comparative tests and publish results.

Design & Manufacturing

Strict adherence to ETTUS Research’s original schematics and PCB specifications:

• Optimized component placement and trace routing

• Critical controls:
  1. Material selection and impedance matching
  2.Electromagnetic compatibility (EMC)
  3. High-frequency performance
  4. Power supply decoupling
  Enhanced power module design delivers superior performance.

Hardware Configuration

• Frequency Range: 70MHz–6GHz

• Transceiver Channels: 2 TX + 2 RX

• Interfaces:
  1. USB 3.0 (control)
  2. DC power input (6V)

  • External power not required for single-channel operation/GPSDO-disabled mode

  • Mandatory for GPSDO or dual-channel operation

• Core Components:
  1. FPGA: 6 × XC6SLX150 (Spartan series)
  2. RF Transceiver: AD9361 dual-channel IC (max 61.44 MS/s sampling rate)
