Abstract
An electronic device comprises a divider and a first filter. The divider comprises 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. The first filter is coupled to the second terminal.
Claims11
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.
