PURPOSE:To cut off an optional signal source to decrease the effect given to other signal sources and to suppress the generation of an electric power loss, by providing a combination of a switch which short-circuits the signal source and a 1/4 wavelength line between the signal source and an output terminal of an electric power compounding device. CONSTITUTION:A series circuit of high frequency switches 2-1-2-n and 1/4 wavelength lines 3-1-3-n is provided between a single load 5 and each of signal sources 1-1-1-n containing inner impedances 6-1-6-n of an electric power compounding system. The output impedance of the lines 3-1-3-n are decided by the characteristic impedance of the load 5, the output impedances of the sources 1-1-1-n and the number of signal lines connected in parallel to each other. Then optional signal sources 1-1-1-n are cut off to reduce the effects given to other signal sources 1-1-1-n. This suppresses the generation of an electric power loss. |
