<p>An amplifier (140) includes a voltage detector (142) that detects current flowing to a drain terminal of a transistor which amplifies a signal using GaN as a voltage difference by means of voltage conversion, a compensation decision unit (143) that decides whether or not to perform gain compensation based on the voltage difference detected by the voltage detector (142), and a gain compensation unit (145) that performs the gain compensation according to the voltage difference when the compensation decision unit (143) decides to perform the gain compensation. The amplifier may be applied, for example, to a transmitter of a wireless base station.</p> |
