Classification: CPC H  G | IPC G  H

Claim 6:
7. The phase synchronization device according to claim 1, wherein
the phase shifter of each of the first and second elements is a bidirectional phase shifter,
the bidirectional phase shifter of the first element outputs, as the stage one second signal, a signal obtained by shifting a phase of the stage one third signal by the first phase shift amount to the phase interpolator of the second element, and
the phase comparator of the first element detects a phase difference between the stage one third signal and the stage one fourth signal obtained by shifting a phase of the stage two first signal output from the second element by the first phase shift amount by the bidirectional phase shifter of the first element, and
the control circuit of the first element controls the first phase shift amount for the bidirectional phase shifter on a basis of the phase difference detected by the phase comparator of the first element.
