  • Tunable ferroelectric resonator arrangement
    Patent number: 7069064
    Abstract: The present invention relates to a tunable resonating arrangement comprising a resonator apparatus (10), input/output coupling (4) means for coupling electromagnetic energy into/out of the resonator apparatus, and a tuning device (3) for application of a biasing voltage/electric field to the resonator apparatus. The resonator apparatus comprises a first resonator (1) and a second resonator (2). Said first resonator is non-tunable and said second resonator is tunable and comprises a ferroelectric substrate (21). Said first and second resonators are separated by a ground plane (13) which is common for said first and second resonators, and coupling means (5) are provided for providing coupling between said first and second resonators. For tuning of the resonator apparatus, the biasing voltage/electric field is applied to the second resonator (2).

  • Tunable microwave devices
    Patent number: 6433375
    Abstract: An electrically tunable device, particularly for microwaves, includes a carrier substrate, conductors, and at least one tunable ferroelectric layer. Between the conductors and the tunable ferroelectric layer, a buffer layer including a thin film structure having a non-ferroelectric material is arranged.

  • Arrangement and method relating to tunable devices through the controlling of plasma surface waves
    Patent number: 6187717
    Abstract: A tunable microwave monolithic integrated circuit includes a dielectric material with a variable dielectric constant. A superconducting material with a negative dielectric constant is provided which is arranged in relation to the dielectric material in such a way that at least one interface is formed between the superconducting material and the dielectric material. The dielectric material is a low loss non-linear bulk material. Phase velocity tuning of microwaves is provided through controlling the propagation of surface plasma waves of the microwaves along the interface(s).
