<p>Provided are a distribution unit (3) for distributing a high-frequency signal inputted via an input terminal (1) into two signals, a main amplification unit (4) connected to one output side of the distribution unit (3), for amplifying a high-frequency signal from the unit (3), an auxiliary amplification unit (5) connected to the other output side of the unit (3), for not operating when the momentary power of a high-frequency signal is small but amplifying a high-frequency signal from the unit (3) when it is large, and a circulator (6) for feeding a high-frequency signal amplified by the unit (5) to the output side of the main amplification unit (4) and a high-frequency signal amplified by the unit (4) to an output terminal (2).</p> |
