CBX
From Ettus Knowledge Base
Contents
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 does not provided phase coherent operation, and therefore is not recommended for MIMO and Phased Array applications.
