摘要： Methods and apparatus for a frequency selective limiter (FSL) having a magnetic material substrate that tapers in thickness and supports a transmission line that has segments and bends. The segments, which differ in width and are substantially parallel to each other, such that each segment traverses the substrate on a constant thickness of the substrate.

摘要： A frequency selective limiter (FSL) is provided having a transmission line structure with a tapered width. The FSL includes a substrate having a magnetic material, a signal (or center) conductor disposed on the substrate and first and second ground plane conductors disposed on the substrate. The signal conductor having a first end with a first width and a second end with a second different width such that the signal conductor is provided having a taper between the first and second ends of the signal conductor. First and second ground plane conductors are spaced apart from first and second edges of signal conductor, respectively, by a distance that changes from the first end of signal conductor to the second end of signal conductor such that signal conductor, and first and second ground plane conductors form a co-planar waveguide transmission line.

摘要： A frequency tunable device includes a substrate, and a capacitor structure supported by the substrate and including a ferroelectric film and first and second electrodes. The ferroelectric film has two opposite sides, and is made from a ferroelectric material having a formula of Pb1−xBaxZrO3, where x is a positive number greater than 0.3 and less than 0.6. The first and second electrodes are respectively formed on the sides of the ferroelectric film. The dielectric constant of the ferroelectric film varies with a voltage applied to the first and second electrodes.

摘要： A magnetostatic-wave device includes a dielectric substrate on which parallel first electrically conductive lines are formed. A magnetostatic-wave device formed of a gadolinium-gallium-garnet (GGG) substrate on which yttrium-iron-garnet (YIG) thin films are formed is disposed on the first electrically conductive lines. Crossed second electrically conductive lines are formed on a YIG thin film. Lands are formed at both ends of these electrically conductive lines and are connected to each other with bonding wire to form one electrically conductive line. Input and output ends are formed between both ends of this electrically conductive line and the ground.
