<P>PROBLEM TO BE SOLVED: To adjust the phase/gain of a power amplifier promptly and appropriately without need for a special apparatus and without need for manpower, and to shorten a required time for adjustment. <P>SOLUTION: A transmitter control device includes composite level detection means that is used in a transmitter for transmitting a synthesized output obtained by passing transmission signals through a reducer and power-amplifying the signals with a plurality of power amplifiers arranged in parallel and synthesizing them with a synthesizer and that detects an output level of the synthesizer, and phase control means that performs phase control of the plurality of power amplifiers so that an output level detected by the composite level detection means is maximum. <P>COPYRIGHT: (C)2012,JPO&INPIT |
