DIELECTRIC RESONANT APPARATUS |
摘要 |
Electrodes are formed on respective two main surfaces of a dielectric sheet wherein each electrode has an opening formed at a location corresponding to the location of the opening formed in the other electrode. The part defined by the openings serves as a dielectric resonator. Coupling lines are formed directly in the electrode opening. Transmission lines are formed on a circuit board. The coupling lines and the corresponding transmission lines are connected to each other via bonding wires. This structure makes it possible to minimize the external Q of a resonant circuit using the dielectric resonator. If an oscillator is produced using this resonant circuit, it is possible to achieve a large frequency modulation with and large output.
