Signal transmission network for millimeter wave imaging equipment and millimeter wave imaging equipment

The utility model discloses a signal transmission network for millimeter wave imaging equipment and the millimeter wave imaging equipment. The signal transmission network comprises a plurality of signal transmission modules arranged in an array, each signal transmission module comprises a switch unit and a power division unit, and the switch unit comprises a first switch, a second switch and a third switch; the first switch opens a corresponding output end radio frequency channel of the switch chip according to a control end potential signal, so that an input radio frequency signal of the signal source is output to the second switch or the third switch; each of the second switch and the third switch comprises four output ends, and the second switch is used for opening a radio frequency channel of the corresponding output end to output a radio frequency signal according to a potential signal of the control end of the second switch; the third switch uses the same control end potential signal as the second switc
