摘要： A transducer has natural unidirectionality for surface acoustic waves. An interdigital electrode structure is arranged on a piezoelectric crystal substrate and is constructed with interdigital transducers including collecting electrodes and fingers. At least two of the fingers form a transducer cell, which includes at least one excitation center for exciting an electrical potential wave and at least one reflection center for reflecting electrical potential waves. The fingers are oriented perpendicularly to a direction R parallel to a 1- or 3-fold rotational axis of the substrate crystal and the derivative dv/dθ=0 applies to R, wherein v is the phase velocity of the surface wave and θ is an angular deviation of the perpendicular to the finger direction from the direction R.

摘要： The invention relates to a transducer having natural unidirectionality for surface acoustic waves, wherein an interdigital electrode structure is arranged on a piezoelectric crystal substrate and is constructed with interdigital transducers comprising collecting electrodes and fingers, wherein at least two of the fingers form a transducer cell, which comprises at least one excitation center for exciting an electrical potential wave and at least one reflection center for reflecting electrical potential waves. The invention is based on the problem of finding materials, material sections, and propagation directions for transducers having natural unidirectionality that result in a low insertion loss even in broadband transducers, and for which the frequency position is not affected or is affected only slightly by errors in the orientation of the electrode structure on the substrate despite the unidirectional characteristics of the transducers. According to an essential characteristic of the invention, the fingers are oriented perpendicularly to a direction R, wherein the direction R is directed parallel to a 1- or 3-fold rotational axis of the substrate crystal and the derivative dv/dθ=0 applies to R, wherein v is the phase velocity of the surface wave and θ is an angular deviation of the perpendicular to the finger direction from the direction R. According to a further characteristic of the invention, the electrode materials and the layer thicknesses thereof are selected in such a way that the phase shift Φs between the excitation center and a reflection center in each transducer cell, given by the equation sin2(Φs)=(ωo2−ωa2) (ωa2−ωo1)/(ωs2−ωs1)(ωo1+ωo2−ωs1−ωa2), lies between 41.4° and 48.6° or between −48.6° and −41.4° or between 131.4° and 138.6° or between −138.6° and −131.4°. The transducer according to the invention can be used in particular for sensors, identification components (ID tag), resonators, filter, delay lines, and oscillators insofar as the mode of operation thereof is based on surface acoustic waves.

摘要： A resonator filter cascade has resonator structures disposed adjacent to one another and form a waveguide for acoustic surface waves, and coupling transducers. The present invention changes resonator filter cascades so that the insertion attenuation is reduced by decreasing the attenuation of cascading, without using a coupling coil. A resonator filter cascade has resonator structures having coupling transducers which transversely couple resonator filters and the coupling transducers, belonging the same transversely coupled resonator filter, are not connected with one another. Coupling transducers of different transversely coupled resonator filters are each connected with one another over a pair of electrically conducting connections.

摘要： An oscillator circuit includes a combination of two frequency-determining elements, designed as single-port surface wave resonators with interdigital converters, and one active electronic circuit. The two single-port surface wave resonators are connected to each other, avoiding inductive components. In the case of a combination in a parallel circuit, the connection is designed as a combination oscillating at high-frequency anti-resonance, and in the case of a combination in a series circuit, the combination is designed as a combination oscillating at high-frequency resonance. A ratio of apertures of the interdigital converters to one another, a ratio of their number of prongs to one another, and the thickness of the electrode layer of the single-port surface wave resonators as well as the propagation direction for acoustic surface waves of the single-port surface wave resonators are selected so that the temperature-dependent change of the phase of the combination and the temperature-dependent change of the total phase of the rest of the elements of the oscillator circuit have signs opposite to one another and that the sum of these phase changes in a thermal operating range of the oscillator circuit is smaller than a value of the phase change of the combination and smaller than a value of the phase change of the rest of the elements of the oscillator circuit.
