TM MODE DIELECTRIC RESONATOR AND TM MODE DIELECTRIC FILTER AND TM MODE DIELECTRIC DUPLEXER.

摘要

A dielectric resonator designed so that there is substantially no loss in a conductor on a shielded cavity surface, and so that the unloaded Q and the resonant frequency can be changed independently of each other. A cylindrical dielectric block 2 having a pair of electrodes 3, 4 formed on its two opposite surfaces is disposed in a metallic shielded cavity 5 so that the electrode 4 is in contact with an inner bottom surface of the shielded cavity 5. This electrode 4 is electrically connected to the shielded cavity 5 or the like.
