UBX

Device Overview

The UBX daughterboard is a full-duplex wideband transceiver that covers frequencies from 10 MHz to 6 GHz. 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 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 UBX is capable of phase coherent operation, and therefore is suitable for MIMO and Phased Array applications, on the X Series. Additionally this capability is only available on the X Series devices.

Key Features

Frequency Range: 10 MHz - 6 GHz Versions: 40MHz / 160MHz RF shielding Full duplex operation with independent TX and RX frequencies Synthesizer synchronization for applications requiring coherent or phase-aligned operation, supported on USRP X Series motherboards only

Important Notes

• A larger 24W (6V, 4A) power supply is required when using a UBX-40 daughterboard and integrated GPS Disciplined Oscillator accessory together in a USRP2, USRP N200, or USRP N210 device.
• The UBX-160 transmitter path has 160 MHz of bandwidth throughout the full frequency range of the device; the receiver path has 84 MHz of bandwidth for center frequencies from 10 MHz to 500 MHz.
