  • Patent number: 11137457
    Abstract: A magnetic field sensor element with a piezo electric substrate having predetermined shear wave velocity VS, two pairs of interdigital electrodes, arranged on the substrate on the ends of a delay section, having a period length p of at least 10 micrometers, a non-magnetic, electrically non-conductive guide layer arranged on the substrate along the delay section, and a magnetostrictive functional layer arranged on the guide layer, wherein the shear wave velocity in the guide layer is smaller than VS, wherein a) the substrate is oriented to generate and propagate mechanical shear waves upon applying a temporally periodic, electrical voltage to at least one interdigital electrode pair in the range of frequency VS/p and, wherein b) the thickness of the guide layer equals at least 10% and at most 30% of the period length p of the interdigital electrodes.

  • Patent number: 8451073
    Abstract: The present invention relates to a resonator device having a stacked arrangement of laminated layers including a plurality of dielectric layers, and at least one resonator comprising a short-circuit electrode, a first capacitor electrode and a second capacitor electrode. Each electrode comprises at least a portion of a layer of electrically conductive material provided on a surface of one of the dielectric layers. The second capacitor electrode is disposed spaced, in the stacking direction, from the short-circuit electrode and the first capacitor electrode. The short-circuit electrode and the second capacitor electrode are electrically interconnected by a first electrical connection comprising at least one via hole penetrating one or more of the dielectric layers.

  • Publication number: 20060220765
    Abstract: The present invention relates to a microwave band-pass filter comprising a plurality of coupled resonators including at least one coaxial resonator (1). For suppression of higher order or spurious pass-bands the filter is characterised in that a central hole (9) extends from the upper end of the inner conductor (6) of said at least one coaxial resonator through at least part of the length of the inner conductor, the central hole (9) forming a wave guide section, the cut-off frequency of which being above the pass-band of the band-pass filter, and in that the wave guide section contains in an upper portion (11) thereof a low loss dielectric material with a dielectric constant sufficiently high so that the cut-off frequency of the wave guide section is below the first higher order response of the band-pass filter, and in that the lower end portion (10) of the central hole (9) contains a lossy material.
