USRP B200mini-i
The USRP™ B200mini-i delivers a 1x1 SDR/cognitive radio in the size of a business card. With a wide frequency range from 70 MHz to 6 GHz and a user-programmable, industrial-grade Xilinx Spartan-6 XC6SLX75 FPGA, this flexible and compact platform is ideal for both hobbyist and OEM applications. The RF front end uses the Analog Devices AD9364 RFIC transceiver with 56 MHz of instantaneous bandwidth. The B200mini-i is bus-powered by a high-speed USB 3.0 connection for streaming data to the host computer. The USRP B200mini-i also includes connectors for GPIO, JTAG, and synchronization with a 10 MHz clock reference or PPS time reference input signal. The USRP Hardware Driver™ (UHD) software API supports all USRP products and enables users to efficiently develop applications then seamlessly transition designs between platforms as requirements expand.
