Device Overview
The BasicRX/BasicTX daughterboards are low-cost daughterboards that provides direct access to the ADC inputs. The boards accept real-mode only signals from 1 to 250 MHz. The BasicRX/BasicTX is ideal for applications using an external front end providing relatively clean signals within operable bandwidth. Wideband transformers couple each RF input to a single channel of the USRP device's ADC. The signals sampled by the ADC are manipulated in the FPGA, and the outputs can be processed independently, or as a single I/Q pair. The BasicTX/BasicRX daughterboards are supported by the USRP Hardware Driver™ (UHD) software API for seamless integration into existing applications.

Daughterboard Specifications
Frontends
BasicRX
The BasicRX has 4 frontends:
- Frontend A: real signal on antenna RXA
- Frontend B: real signal on antenna RXB
- Frontend AB: quadrature frontend using both antennas (IQ)
- Frontend BA: quadrature frontend using both antennas (QI)
BasicTX
The BasicTX has 4 frontends:
- Frontend A: real signal on antenna TXA
- Frontend B: real signal on antenna TXB
- Frontend AB: quadrature frontend using both antennas (IQ)
- Frontend BA: quadrature frontend using both antennas (QI)
Gains
BasicRX
- The BasicRX has no tunable elements or programmable gains. Through the magic of aliasing, you can down-convert signals greater than the Nyquist rate of the ADC.
BasicTX
- The BasicTX has no tunable elements or programmable gains. Through the magic of aliasing, you can up-convert signals greater than the Nyquist rate of the DAC.
Bandwidths
BasicRX
- For Real-Mode (A or B frontend): 250 MHz
- For Complex (AB or BA frontend): 500 MHz
BasicTX
- For Real-Mode (A or B frontend): 250 MHz
- For Complex (AB or BA frontend): 500 MHz
Input/Output Impedance
- All RF Ports are matched to 50 Ohm with -10dB or better return loss generally. Detailed test is pending.
