why DC offset affects the performance of Zero-IF

Hi, there,
This is a conceptual question, why does DC offset affect the performance of direct-conversion RF receiver?

TIA.

DC offset potentially shifts DC operating points of following gain stages, saturating them, causing signal clipping and reducing amplifier's input sensitivity and dynamic range. Of course, this is bad for zero-IF since the DC component is right in desired signal bandwidth and hard to be discriminated.

also the DC can saturate the DAC used in the Baseband so the signal will be totally lost

also in the ZIF , the scond order intermodulation product are very critical "need to be minimized"
