摘要： A voltage tunable dielectric varactor includes a tunable ferroelectric layer and first and second non-tunable dielectric layers. First and second electrodes positioned adjacent to the tunable ferroelectric layer form a tunable capacitor. A third electrode is positioned adjacent to the first non-tunable dielectric layer such that the third and first electrodes and the first non-tunable dielectric layer form a first blocking capacitor. A fourth electrode is positioned adjacent to the second non-tunable dielectric layer such that the fourth and second electrodes and the second non-tunable dielectric layer form a second blocking capacitor. The first and second electrodes can be positioned on a surface of the tunable ferroelectric layer opposite the generally planar surface of the substrate, with the first and second electrodes being separated to form a gap. The first and second non-tunable dielectric layers can also be positioned on the generally planar surface of the substrate. The third electrode can be positioned on the surface of the first non-tunable dielectric layer opposite the generally planar surface of the substrate such that the third and first electrodes form a second gap. The fourth electrode can be positioned on the surface of the second non-tunable dielectric layer opposite the generally planar surface of the substrate such that the fourth and second electrodes form a third gap.
