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.

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
