Abstract

A power source supply circuit includes: a plurality of power sources (--) that generate power source voltages different from each other; a switch circuit () that switches and outputs the power source voltages generated in the plurality of power sources (--); a voltage output terminal () that outputs outside the power source voltages output from the switch circuit (); an RF choke circuit () provided between the switch circuit () and the voltage output terminal (), the RF choke circuit () including a first capacitor; and a second capacitor (--) provided between the plurality of power sources (--) and the switch circuit (), the second capacitor (--) having a larger capacitance than the first capacitor.
