Abstract: PURPOSE: A multiport amplifier and an amplification method are provided to perform automatic correction by providing a circuit and a set up method for setting a phase/amplitude adjustment value. CONSTITUTION: A size/phase adjusting circuit(450) performs fine correction and coarse correction. The coarse correction performs the reversion of 0 or 180 degrees. The coarse correction changes a port position of an output signal. Phase correction is performed by each part connect node and mismatch properties. The size/phase adjusting circuit is arranged in the front end of a high power amplifier(440) in order to prevent power loss from an output terminal. An output terminal hybrid network(430) improves isolation performance of a multiport amplifier by maintaining a size and a phase difference of a signal to be the same as in an ideal multiport amplifier. An input hybrid network(420) includes 4 hybrids(410).
