Digilent Ettus BasicTX – Daughterboard for Ettus USRP N210, 1 – 250 MHz Tx

• Transmit Only
• Frequency range: 1 – 250 MHz
• Channel count: 1 TX intermediate frequency (IF) or 1 quadrature interface (IQ)
• Bandwidth: 100 MHz/Channel
• Outputs can be operated independently or combined into a single I/Q pair

The BasicTx daughterboard is a low-cost daughter board that provides transmission capability from the USRP from 1 to 250 MHz. The BasicTx uses two wideband transformers to match the dual DAC outputs of a USRP to 50-ohm SMA connections.

The wide bandwidth of the BasicTx board allows the USRP to operate in a subsampling mode when the desired output frequency is beyond the sampling clock rate of the USRP DACs. Each output of the BasicTx can be operated independently or combined into a single I/Q pair. Note that appropriate filtering should be utilized in subsampling modes.

Example applications include transmitters with external RF front ends direct generation of baseband of passband signals and custom daughtercard development.
