Multilayer electronic component

A multilayer electronic component comprising:

• a stack;
• a balun formed using the stack;
• and
• a branching circuit that is formed using the stack and connected to the balun, wherein
• the stack includes a plurality of dielectric layers and a plurality of conductor layers stacked on each other,
• the balun includes:
• an unbalanced port;
• a first balanced port;
• a second balanced port;
• an unbalanced transmission line including a first line portion and a second line portion connected in series;
• a first balanced transmission line and a second balanced transmission line configured to be electromagnetically coupled to the first line portion;
• and
• a third balanced transmission line and a fourth balanced transmission line configured to be electromagnetically coupled to the second line portion;
• each of the first and second line portions and first to fourth balanced transmission lines has a first end and a second end opposite to each other,
• the first end of the first line portion is connected to the unbalanced port,
• the second end of the first line portion is connected to the second end of the second line portion,
• the first end of the first balanced transmission line and the first end of the second balanced transmission line are connected to the first balanced port,
• the first end of the third balanced transmission line and the first end of the fourth balanced transmission line are connected to the second balanced port,
• each of the first and second line portions and first to fourth balanced transmission lines is formed using at least one of the plurality of conductor layers,
• the branching circuit includes a first filter and a second filter connected to the unbalanced port,
• the first filter selectively passes a first signal of a frequency within a first frequency band, and
• the second filter selectively passes a second signal of a frequency within a second frequency band higher than the first frequency band.
