Dielectric filter with variable central frequency |
摘要 |
A dielectric filter with variable central frequency is provided comprising at least one dielectric resonator formed from a dielectric ceramic body covered with electrodes as well as electromagnetic input and output means for coupling the signal to and from the filter. According to the invention, the filter further comprises a variable capacity connected between the electrodes of the resonator, in a capacitive zone of said resonator, for continuously varying the central frequency of said filter.
