In stock at distributor Mouser Electronics is the B200mini Ettus USRP 70MHz-6GHz SDR/cognitive radio from Digilent.

This is a flexible and compact platform, ideal for hobbyist and OEM applications.

The B200mini offers a wide frequency range and a user-programmable Spartan-6 XC6SLX75 FPGA from Xilinx, all in the size of a business card. The comparable Ettus USRP B205mini-i is an industrial temperature version with a larger FPGA for more advanced applications.

The RF front end utilises the AD9364 RF transceiver from Analog Devices with 56MHz instantaneous bandwidth. The board is bus-powered by a high-speed USB 3.0 connection for streaming data to the host computer.

Additionally, the USRP B200mini includes connectors for GPIO, JTAG, and synchronization with a 10MHz clock reference or PPS time reference input signal.

The Digilent B200mini Ettus USRP SDR/cognitive radio allows flexibility across various applications, including FM and TV broadcast, cellular, GPS, WiFi, ISM, and more. Prototyping can begin immediately in GNU Radio and participate in the open-source SDR community.

Full support by the USRP Hardware Driver (UHD) software enables seamless code reuse from existing designs, compatibility with open-source applications like HDSDR and OpenBTS, and an upgrade path to industry-ready USRP systems to meet application requirements.

Applications include software-defined radio, radio astronomy, Industrial, Scientific, and Medical (ISM), radar, cellular communication, GPS, Wi-Fi, OTA TV and radio broadcasting, media streaming and aviation transponders.
