1. An electronic device comprising:
- a first coupler having a first terminal for inputting a high-frequency signal, a second terminal coupled to the first terminal, and third and fourth terminals for distributing thereto the signal inputted from the first terminal;
a first filter coupled to the second terminal; and
a first line having one end connected to the third terminal and the other end connected to the fourth terminal;
wherein the first filter has a capacitor connected between the second terminal and a reference potential and a second line having one end connected to the second terminal and the other end left open, the first line having a line length twice that of the second line.
