    55The radio transceiver on the WARP Radio Board uses a direct conversion architecture. One side-effect of this is a sensitivity to DC offsets in the transmitted signal. Any DC component in the transmit waveform results in carrier leakage at RF. In addition to any DC component in the user's transmitted waveform, the radio board itself introduces a small DC offset due to variations in component values and board assembly.

    7 To avoid these problems, users should be careful to transmit waveforms with zero DC component, and should calibrate their radios.
