NI / Ettus Research UBX-40 Full-Duplex Wideband Transceiver Daughterboard Description

Functions

Provides full-duplex RF transceiver capabilities operating from 10 MHz to 6 GHz with 40 MHz instantaneous bandwidth. Implements direct conversion architecture with integrated synthesizers, mixers, and gain stages for transmit and receive chains. Interfaces with USRP motherboards via high-speed digital interface for baseband I/Q sample transfer. Supports independent TX/RX tuning, variable gain control, and antenna switching. Enables software-defined radio applications including wireless communications prototyping, spectrum monitoring, cognitive radio research, and RF test instrumentation. Compatible with GNU Radio, LabVIEW, and other SDR frameworks for signal processing implementation.

Platforms

Designed for USRP X-Series and N-Series software-defined radio mainboards, it connects via an internal daughterboard header for direct FPGA interfacing, enabling I/Q data streaming and control. External connections consist of two SMA connectors for separate transmit and receive RF signal paths, interfacing with antennas or RF front-end equipment. Operator control is managed through a host computer utilizing the USRP Hardware Driver (UHD) API, enabling integration with software applications such as GNU Radio, LabVIEW, or MATLAB for signal processing and system control.

Applications

Transceiver daughterboard designed for software-defined radio (SDR) applications enabling full-duplex wireless communications across 10 MHz to 6 GHz frequency range with up to 160 MHz instantaneous bandwidth. Features integrated local oscillators, mixers, filters, and amplifiers for RF signal processing. Compatible with USRP (Universal Software Radio Peripheral) hardware platforms, connecting through high-speed digital interfaces. Commonly used in wireless communications research, spectrum monitoring, cellular base station prototyping, cognitive radio experiments, radar systems, and satellite communications.

Accessories

Requires USRP mainframe such as X310, X300, N210, or B210 series with daughterboard slots. Standard 100-pin high-speed board-to-board connector interface. SMA connectors for TX1/TX2 RF outputs and RX1/RX2 RF inputs. Requires external antenna connections via SMA cables. Clock and data signals provided through mainframe backplane connection. No external power supply needed as power supplied through mainframe. Compatible with GNU Radio software framework and USRP Hardware Driver.

Interfaces

Requires compatible USRP X-Series or N-Series mainframe via proprietary high-density board-to-board daughterboard headers. RF I/O: One SMA female connector for TX/RX path, one SMA female connector for RX2 path. Required Accessories: RF coaxial cables with SMA male connectors, antennas.

Specifications

Wideband RF transceiver daughterboard operating from 10 MHz to 6 GHz with 40 MHz instantaneous bandwidth.
