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

Key Features

Frequency Range: 50MHz - 2.2GHz Versions: 40MHz / 120MHz Power Output: 100mW Noise Figure: 5dB

Daughterboard Specifications

Features

• 2 quadrature frontends (1 transmit, 1 receive)
  • Defaults to direct conversion
  • Can be used in low IF mode through lo_offset with uhd::tune_request_t
• Independent receive and transmit LO's and synthesizers
  • Allows for full-duplex operation on different transmit and receive frequencies
  • Can be set to use Integer-N tuning for better spur performance with uhd::tune_request_t

Antennas

Transmit: TX/RX

Receive: TX/RX or RX2

• Frontend 0: Complex baseband signal for selected antenna
• Note: The user may set the receive antenna to be TX/RX or RX2. However, when using a WBX board in full-duplex mode, the receive antenna will always be set to RX2, regardless of the settings.

Gains

• Transmit Gains: PGA0, Range: 0-25dB
• Receive Gains: PGA0, Range: 0-31.5dB

Bandwidths

• WBX: 40 MHz, RX & TX
• WBX-120: 120 MHz, RX & TX

Sensors

• lo_locked: boolean for LO lock state

Hardware Specifications

• Ettus Research recommends to always use the latest stable version of UHD

WBX-40

• Current Hardware Revision: 1
• Minimum version of UHD required: 3.8.0

WBX-120

• Current Hardware Revision: 1
• Minimum version of UHD required: 3.8.0

Environmental Specifications

Operating Temperature Range

• 0-40 °C

Operating Humidity Range

• 10% to 90% non-condensing

USRP Compatibility

WBX-40

• N or X Series

WBX-120

• X Series only
