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 flexible transceiver architecture features multiple reconfigurable RF signal paths to optimize performance across a wide frequency range. A down conversion stage in the transmitter path, and an up conversion stage in the receiver path, extends the tuning range of the main direct conversion stage to cover signals with a center frequency from 10 MHz to 500 MHz. The wide RF coverage of the UBX daughterboard is ideal for applications spanning all the most common bands of interest such as HF, VHF, cellular, radar, and Wi-Fi.
