<P>PROBLEM TO BE SOLVED: To provide radio equipment capable of diagnosing a present apparatus in the state of continuing an operation without enlarging the scale of the apparatus, and its control method. <P>SOLUTION: The radio equipment (100) with a self diagnosing function, which is provided with an antenna (ANT) for transmitting and receiving signals and a demultiplexer (DUP) for separating the transmission route (120) of transmission signals and the reception route (130) of reception signals, includes: a distribution part (140) for distributing the transmission signals from the transmission route (120) in the prestage of the demultiplexer (DUP); a phase shifter (150) for adjusting the phase of the transmission signals distributed in the distribution part (140); a connection part (160) for connecting the transmission signals whose phase is adjusted in the phase shifter (150) to the reception route (130) in the poststage of the demultiplexer (DUP); and a control part (114) for controlling the phase shifter (150) so as to turn the phase of the transmission signals distributed in the distribution part (140) to the same phase as the phase of the transmission signals which flow into the reception route (130) through the demultiplexer (DUP). <P>COPYRIGHT: (C)2010,JPO&INPIT |
