Abstract
A satellite-broadcasting receiving converter includes a plurality of output terminals each of which is connected to an external receiver, to each of which a selection control voltage in which a high-frequency voltage is superposed on a DC voltage is sent from the external receiver, and from each of which one type of a receiving signal is selected according to the selection control voltage and output; and a regulator for generating a power-source voltage from the selection control voltage. Since a high-frequency attenuation unit is connected in series between each output terminal and the regulator in the satellite-broadcasting receiving converter, even if a plurality of selection control voltages are input in common to the regulator, the plurality of selection control voltages different from each other do not affect each other and thereby only one regulator is required.
