PROBLEM TO BE SOLVED: To provide a synthesizer in which the effective relative permittivity in odd mode is prevented from becoming larger than that in even mode, and an increase in return loss and impact on deterioration of isolation can be reduced.SOLUTION: A synthesizer includes a printed board, first and second conductor plates, and first and second conductors. A hole penetrating from the first surface to a second surface on the reverse side of the first surface is formed in the printed board. The first conductor plate is mounted on the first surface of the printed board so as to close the hole, and consists of a copper plate. The second conductor plate is mounted on the second surface of the printed board so as to close the hole, and consists of a copper plate. The first conductor is disposed to face the first conductor plate, with a space of a predetermined interval therebetween. The second conductor is disposed to face the second conductor plate, with a space of a predetermined interval therebetween. |
