Irreversible circuit element |
| 摘要 |
<p>A magnetic yoke (1) also serves as a case for an irreversible circuit element. The magnetic yoke has a surface which is covered with a high-conductivity metal coating film having an electric resistivity of 5.5 mu OMEGA cm or less. Thereby, signal energy is efficiently maintained. An input signal is transmitted to an output terminal with less loss. <IMAGE></p> |
