For price see pricelist


UBX 40 USRP Daughterboard (10 MHz - 6 GHz, 40 MHz BW)


  • Wide Frequency Range: 10 MHz - 6 GHz
  • Bandwidth and Compatibility: 40 MHz Bandwidth (N200/N210/X300/X310)
  • RF shielding
  • Full duplex operation with independent TX and RX frequencies
  • Synthesizer synchronization for applications requiring phase coherence or alignment


The UBX 40 daughterboard is a full-duplex, wideband transceiver tunable to frequencies from 10 MHz to 6 GHz with an instantaneous bandwidth of 40 MHz. It delivers the highest performance RF of all direct conversion USRP daughterboards across all frequency bands with the added capability of achieving coherent and phase-aligned operation across multiple channels for MIMO and direction finding applications. The wide tuning range makes the UBX ideal for applications across all of the most common frequency bands spanning HF, VHF, cellular, radar, and WIFI with the instantaneous bandwidth necessary for monitoring entire bands of interest and prototyping next generation wireless communication systems.  

The UBX daughterboard works interchangeably with existing USRP daughterboards and can be seamlessly integrated into your existing applications with the latest version of the open source USRP Hardware Driver (UHD) software.
