Abstract: PURPOSE: An apparatus for correcting amplitude and phase errors and a multiport amplifier including the same and an amplifying method thereof are provided to automatically correct phase and amplitude errors of a multiple output amplifier due to environmental condition changes including deterioration or temperature changes of component performance using an error correction function. CONSTITUTION: An input hybrid network(10) generates a plurality of radio frequency signals using an input radio frequency signal. A plurality of power amplifiers(31-34) amplifies the plurality of radio frequency signals. An output hybrid network(20) generates one or more output RF signals from an output signal of the plurality of power amplifiers. An error detection unit detects an amplitude error and a phase error about the output signal of the plurality of power amplifiers by comparing one or more QPSK(Quadrature Phase Shift Keying) signals with a reference QPSK signal. A plurality of amplitude and phase controllers controls the phase and amplitude of the plurality of radio frequency signals according to the amplitude error the phase error.
