Device Overview

The WBX is a wide bandwidth transceiver that provides up to 100 mW of output power and a noise figure of 5 dB. The LO's for the receive and transmit chains operate independently. The WBX daughterboard is supported by the USRP Hardware Driver™ (UHD) software API for seamless integration into existing applications.

The WBX provides phase coherent operation, although with a 180-degree ambiguity, which must be calibrated out in the application. For phase-coherent applications, Ettus Research recommends the SBX with the N200/N210 or the SBX or UBX with the X300/X310.

Key Features

  • Frequency Range: 50MHz - 2.2GHz
  • Versions: 40MHz / 120MHz
  • Power Output: 100mW
