ABSTRACT OF THE DISCLOSURE A battery-powered radio communication apparatus is disclosed which comprises a power amplifier, a power detector for detecting the output power of the power amplifier. A supply voltage detector compares a standard voltage with the output voltage of a battery which supplies power to the power amplifier. A gain control circuit controls the gain of the power amplifier in response to the output of the power amplifier and to the output of the supply voltage detector so as to prolong by a certain time the communicable state of the apparatus.
