Multilayer power splitter

A multilayer power splitter characterized by comprising:

• a laminate of roughly rectangular solid shape constituted by multiple insulator layers stacked together;
• internal conductors embedded in the laminate;
• an input port formed on a side face of the laminate and electrically connected to the internal conductors;
• an inter-layer connection terminal formed on a side face of the laminate and used to electrically interconnect the internal conductors formed on different insulator layers;
• and first through third output ports formed on a side face of the laminate and electrically connected to the internal conductors;
• wherein the internal conductors comprise:
• a first spiral coil conductor;
• a second spiral coil conductor positioned in a manner facing the first coil conductor via an insulator layer;
• a third spiral conductor positioned where it does not overlap with the first coil conductor in a laminating direction;
• a fourth spiral conductor positioned in a manner facing the third coil conductor via an insulator layer;
• a first connection conductor that electrically connects the input port to one end of the first coil conductor;
• a second connection conductor that electrically connects the first output port and the other end of the first coil conductor;
• a third connection conductor that electrically connects the input port and one end of the second coil conductor;
• a fourth connection conductor that electrically connects the inter-layer connection terminal and the other end of the second coil conductor;
• a fifth connection conductor that electrically connects the inter-layer connection terminal and one end of the third coil conductor;
• a sixth connection conductor that electrically connects the second output port and the other end of the third coil conductor;
• a seventh connection conductor that electrically connects the connection port and one end of the fourth coil conductor;
• and
• an eighth connection conductor that electrically connects the third output port and the other end of the fourth coil conductor;
• where the first coil conductor and second coil conductor are positioned in such a way that current flows in opposite directions;
• the third coil conductor and fourth coil conductor are positioned in such a way that current flows in opposite directions;
• an inductance ratio of the first coil conductor and second coil conductor is 4:1;
• and
• an inductance ratio of the third coil conductor and fourth coil conductor is 1:1.
