The CBX is a full-duplex, wideband transceiver that covers a frequency band from 1.2 GHz to 6 GHz with a instantaneous bandwidth of 40 MHz or 120 MHz. The CBX can serve a wide variety of application areas, including WiFi research, cellular base stations, cognitive radio research, and RADAR. The CBX daughterboard is supported by the USRP Hardware Driver™ (UHD) software API for seamless integration into existing applications.
 +
 
 +
The CBX does not provided phase coherent operation, and therefore is not recommended for MIMO and Phased Array applications.

Device Overview

The CBX is a full-duplex, wideband transceiver that covers a frequency band from 1.2 GHz to 6 GHz with a instantaneous bandwidth of 40 MHz or 120 MHz. The CBX can serve a wide variety of application areas, including WiFi research, cellular base stations, cognitive radio research, and RADAR. The CBX daughterboard is supported by the USRP Hardware Driver™ (UHD) software API for seamless integration into existing applications.

The CBX does not provided phase coherent operation, and therefore is not recommended for MIMO and Phased Array applications.
