Software-defined radio platforms host Xilinx Kintex FPGAs, span DC-6GHz

National Instruments company Ettus Research’s latest software-defined radio platforms incorporate Kintex-7 FPGAs and offer 2x2 MIMO capability

The two platforms each combine two RF transceivers covering DC–6 GHz with up to 120 MHz bandwidth and a large user-programmable Kintex-7 FPGA. The USRP X300 and USRP X310 have multiple high-speed interface options, including PCI Express, dual 10-Gigabit Ethernet and dual 1-Gigabit Ethernet. They come in a desktop or rack-mountable half-wide 1U form factor. The USRP Hardware Driver (UHD) architecture, common to all NI USRP (Universal Software Radio Peripheral) devices, provides a comprehensive interface.

Developers can control the USRP by programming with the UHD C++ API, or choose from a selection of third-party tools and software such as GNU Radio. Ettus/NI cites a flexible software ecosystem that will help you deliver cost-effective, high-performance SDR solutions – you can create simple prototypes, develop complex systems and accelerate wireless research.

The USRP X300 uses the Xilinx Kintex XC7K325T, and the USRP X310 is based on the larger XC7K410T. Kintex-7 FPGAs integrate up to 1,540 DSP48 slices operating in parallel so you can can deploy custom or third-party signal processing algorithms onto each device. Users can process data in real time using their own DSP algorithms such as filters, modulators/demodulators and coders/decoders. They can also access and control the wide range of peripherals available on each USRP, including the RF front ends.

Matt Ettus, Founder and President of Ettus Research adds that with, “...unprecedented levels of real-time signal processing power and RF bandwidth, the USRP X310 and USRP X300 can now address applications such as next generation 5G wireless standard prototyping, multichannel spectrum scanning and analysis and even active radar prototyping and development.”
