摘要： An amplification output control device includes: a determination unit that determines whether or not a gain of a power amplifier varies based on a monitor value of input power from a driver amplifier to the power amplifier, and, when determining that the gain varies, outputs a monitor value of output power of the power amplifier to a driver control unit to cause the driver control unit to execute control of a bias voltage of the driver amplifier; and a control unit that determines whether or not the gain varies based on the monitor value of the output power of the power amplifier when determining that the gain does not vary based on the monitor value of the input power to the power amplifier, and, when determining that the gain varies, controls the bias voltage of the power amplifier.
