The LFRX daughterboard is a low-cost daughterboard that provides direct access to the ADC inputs. The board can accept real-mode or quadrature signals from DC to 30 MHz. The LFRX is ideal for applications using an external front end providing relatively clean signals within operable bandwidth.
LFRX
The HM LFRX daughterboard is a low-cost daughterboard that provides direct access to the ADC inputs. The board can accept real-mode or quadrature signals from DC to 30 MHz. The LFRX is ideal for applications using an external front end providing relatively clean signals within operable bandwidth. High-speed opamps 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 can be processed as two real-mode signals, or a single I-Q pair.
Frequency: 0 – 30MHz
Example applications include HF communications, radios with external front ends and direct signal measurements below 30 MHz.
