| 摘要 |
A high-frequency device having a high-frequency circuit comprising a high-frequency amplifier, and an output-matching circuit receiving high-frequency power output from the high-frequency amplifier, in and on a multilayer substrate obtained by laminating pluralities of dielectric layers, the output-matching circuit comprising a first transmission line transmitting the high-frequency power from the high-frequency amplifier side to the output terminal side, and at least part of the first transmission line being formed by series-connecting pluralities of conductor patterns formed on pluralities of dielectric layers in a laminate direction. |
