National Instruments Ettus USRP X440

This is a high-performance software-defined radio (SDR) designed for the development and prototyping of advanced wireless communication systems.

Key Features:

• Frequency Range: from 30 MHz to 4 GHz, tunable down to 1 MHz.
• Bandwidth: up to 1.6 GHz per channel, with an aggregate bandwidth of up to 3.2 GHz.
• Channels: 8 transmit (TX) and 8 receive (RX) channels, all independently tunable and phase-aligned, making the device suitable for high-density channel applications.
• Architecture: employs a direct conversion architecture with transformer-coupled ADCs and DACs on a Xilinx Zynq UltraScale+ RFSoC ZU28DR-2 chip.
• Synchronization: equipped with a GPS-disciplined OCXO 10 MHz reference generator, enhancing frequency accuracy and synchronization capabilities.
• Performance: includes a quad-core ARM Cortex-A53 processor, supporting both standalone (embedded) and networked operation modes.
• Interfaces: features two 100-gigabit Ethernet (100 Gbps) ports via QSFP28 for high-speed data transfer, as well as additional connectivity options such as 1 Gbps Ethernet, USB Type-C, and HDMI for GPIO.
  
  

Applications:

• Radar Systems: the wide bandwidth and phase-aligned channels make the device ideal for radar research and prototyping.
• Electronic Warfare (EW): supports the development of EW systems requiring high-performance signal generation and analysis.
• Satellite Communication (SATCOM): suitable for SATCOM prototyping and ground station deployment, especially when integrated with custom frontends for extended frequency range.
• Millimeter-Wave Development (mmWave): can be used in mmWave and sub-THz research for 6G when combined with appropriate external frontends.
