Patent ID: 7949314

Claim:
A transmission output control apparatus comprising: a level control circuit operable to adjust a level of an inputted signal; a power amplifying circuit including a plurality of amplifying stages and being operable to amplify the signal whose level has been adjusted by the level control circuit; an antenna operable to transmit the signal amplified by the power amplifying circuit; a memory unit operable to prestore a plurality of control signals; a control signal generating unit operable to select and extract, from the memory unit, one of the control signals that is in accordance with a transmission level instructed by a base station, and supply the extracted control signal to the level control circuit; and a detection unit operable to detect a signal at a midway amplifying stage of the power amplifying circuit, wherein a transmission level of the level control circuit is monitored according to an output of the detection unit, the power amplifying circuit includes at least three amplifiers, and the midway amplifying stage is included in amplifying stages between every two consecutive amplifiers of the at least three amplifiers, and is not the most distant from the level control circuit among the amplifying stages.
