Abstract
In a device for controlling the output power of a power amplifier, an output control signal varies the gain of the power amplifier. A detector detects the output power of the amplifier. A signal processing circuit receives the output of the detector and a control signal from the outside and controls the gain of the amplifier. A EEPROM stores corresponding sets of detection outputs and output control signals each corresponding to particular power to be output from the amplifier. The signal processing circuit reads out from the EEPROM, based on the outside control signal and the output of the detector, a corresponding one of the output control signals. The corresponding output control signal which is read out of the EEPROM is fed to the control terminal of the power amplifier to control its gain.
