Abstract
A varactor-tunable radio frequency (RF) resonant circuit is disclosed. The circuit includes a planar impedance-controlled transmission line disposed on a dielectric substrate, and a voltage-controlled varactor diode, or an arrangement of parallel varactor diodes, electrically connecting a resonator of the planar transmission line to a reference node. The resonator can have a stepped impedance. A frequency of the resonator is tunable by configuration of a reverse bias voltage applied to the first plurality of voltage-controlled varactor diodes.
