Dielectric electronic component and method of adjusting input/output coupling thereof |
摘要 |
The extent of input/output coupling of a dielectric electronic component such as a dielectric filter or a dielectric duplexer can be adjusted by a novel method. The dielectric filter 1 comprises excitation holes whose short-circuiting ends are provided with respective coupling-adjusting countersinks.
