1. A device for controlling output power of a power amplifier, comprising:

  • a power amplifier having a gain variable in response to an output control signal;

    detecting means for detecting output power of said power amplifier;

    signal processing means for feeding said output control signal to said power amplifier in response to a detection output of said detecting means and an outside control signal fed from outside for controlling the output power of said power amplifier; and

    a storage device storing various values of said detection output and various values of said output control signal in correspondence with various values of the power to be output from said power amplifier;

    wherein said signal processing means reads, in response to said detection output and said outside control signal input thereto, a corresponding one of said various values of said output control signal out of said storage, device and feeds the output control signal having said value to said power amplifier to thereby control the gain of said power amplifier.
