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 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.

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

Phase Synchronization
The WBX daughterboard is capable of phase-synchronous operation, but with a with a 180-degree ambiguity, which must be calibrated out in the user application. The SBX, UBX, TwinRX daughterboards are recommended for phase-coherent applications.
