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. The CBX can serve a wide variety of application areas, including WiFi research, cellular base stations, cognitive radio research, and RADAR.
The local oscillators for the receive and transmit chains operate independently, allowing multi-frequency operation. The references for the local-oscillators are derived from the USRP master-clock, which permits coherent operation when combined with MIMO-capable USRP models such as the USRP N200 or USRP N210.
