Electronically tunable combline filters tuned by tunable dielectric capacitors |
摘要 |
A voltage-controlled tunable filter includes at least two cavity resonators electrically coupled to each other. A voltage tunable dielectric capacitor is positioned within each of the resonators. Connections are provided for applying a control voltage to the voltage tunable dielectric capacitors. An input is coupled to the one of the resonators, and an output is coupled to the other resonator.
