The Digilent Ettus USRP N210 is a high-bandwidth, high-dynamic range SDR/cognitive radio available as a standalone unit (Ettus N210) or bundled with the UBX40 daughterboard (Ettus N210 UBX40) or with the LFRX and LFTX daughterboards (Ettus N210 LFRX LFTX).

The USRP N210 is the highest performing class of hardware of the USRP (Universal Software Radio Peripheral) family of products, which enables engineers to rapidly design and implement powerful, flexible software radio systems. The N210 hardware is ideally suited for applications requiring high RF performance and great bandwidth. Such applications include physical layer prototyping, dynamic spectrum access and cognitive radio, spectrum monitoring, record and playback, and even networked sensor deployment. The Networked Series products offers MIMO capability with high bandwidth and dynamic range. The Gigabit Ethernet interface serves as the connection between the N210 and the host computer. This enables the user to realize 50 MS/s of real-time bandwidth in the receive and transmit directions, simultaneously (full duplex).

The USRP N210 provides high-bandwidth, high-dynamic range processing capability and is intended for demanding communications applications requiring this type of rapid development. The product architecture includes a Xilinx Spartan 3A-DSP 3400 FPGA, 100 MS/s dual ADC, 400 MS/s dual DAC and Gigabit Ethernet connectivity to stream data to and from host processors. A modular design allows the USRP N210 to operate from DC to 6 GHz, while an expansion port allows multiple USRP N210 series devices to be synchronized and used in a MIMO configuration.

The USRP N210 can stream up to 50 MS/s to and from host applications. Users can implement custom functions in the FPGA fabric, or in the on-board 32-bit RISC softcore. The FPGA also offers the potential to process up to 100 MS/s in both the transmit and receive directions. The FPGA firmware can be reloaded through the Gigabit Ethernet interface.

The Networked Series MIMO connection is located on the front panel of each unit. Two Networked Series units may be connected to realize a complete 2x2 MIMO configuration using the optional MIMO cable. External PPS and reference inputs can also be used to create larger multi-channel systems. The USRP Hardware Driver is the official driver for all Ettus Research products. The USRP Hardware Driver supports Linux, Mac OSX, Windows.

The UBX 40 daughterboard is a full-duplex wideband transceiver that covers frequencies from 10 MHz to 6 GHz with 40 MHz of instantaneous bandwidth. Coherent and phase-aligned operation across multiple UBX daughterboards on USRP X Series motherboards enables users to explore MIMO and direction-finding applications. The UBX 40 daughterboard works interchangeably with other USRP daughterboards and is supported by the USRP Hardware Driver (UHD) software API for seamless integration into existing applications.

The LFRX daughterboard is a low-cost daughterboard that provides direct access to the ADC inputs. The board can accept real-mode or quadrature signals from DC to 30 MHz. The LFRX is ideal for applications using an external front end providing relatively clean signals within operable bandwidth. High-speed Op-amps couple each RF input to a single channel of the USRP device’s ADC. The signals sampled by the ADC are manipulated in the FPGA and can be processed as two real-mode signals, or a single I-Q pair.

The LFTX daughterboard utilizes two high-speed operational amplifiers to allow transmission from 0-30 MHz. The LFTX is ideal for applications in the HF band, or for applications using an external front end to up-convert and amplify the intermediate signal. The outputs of the LFTX can be processed independently, or as a single I/Q pair. Example applications include HF communications, radios with external front ends and direct signal generation below 30 MHz.
