PROBLEM TO BE SOLVED: To make the weight of a feeder circuit light and to simplify the design by providing a device distributing an output of an amplifier into plural destinations and allowing a distributed destination to adjust an amplitude and a phase to the system. SOLUTION: An input signal is fed to each of small power exciters 4 via an amplifier 1. The higher the power of the signal received by the exciter 4 is, the smaller the power after distribution is, thus this method is desirable. An exciting phase required for forming an antenna beam and an exciting amplitude required for antenna beam forming are provided to each of small power signals to be distributed and the signals are composed by each power combiner. The combined signal becomes again a large power signal and it is emitted from an antenna 3. |
