BasicTX
Daughterboard 1-250 MHz Tx

BasicTX USRP Daughterboard (1 – 250 MHz)
The BasicTX daughterboard provides a simple, wideband interface to the DAC output(s) of a USRP. The BasicTX is an ideal daughterboard for users who want to use an external RF front end, or experiment with the raw signals provided by the USRP. A wideband transformer allows operation from 1 to 250 MHz on each channel.

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
