There is provided an I/Q regeneration device of a five-port network which adopts a single-frequency continuous wave signal in place of a specific modulated signal such as a QPSK signal to estimate an I/Q regeneration parameter of the five-port network. The I/Q regeneration device of the five-port network including: a five-port network distributing an input signal as three signals and adding the three signals to first, second and third carrier signals, respectively to output first, second and third phase signals each having a phase different from one another; a power detection part detecting a power of each of the first, second and third phase signals from the five-port network to output first, second and third power detection signals; and a post-processing part restoring original data in response to the first, second and third power detection signals.
