A thin-film coupler with a carrier substrate ( ) and two strip lines disposed thereon, of which one represents the main coupler loop ( ) and one the auxiliary coupler loop ( ). The use of inexpensive carrier substrate materials and a compact construction are made possible through an integration of a strip line, a coil, or an LC combination into the auxiliary coupler loop ( ). The integration of these components ( ) achieves a phase shift in the frequency of the signal coupled out so that a broadband coupler is obtained which exhibits an identical coupling at at least two frequencies.

Thin-film broadband coupler

The invention relates to a passive ceramic component with a carrier substrate, at least one first electrode, at least one first barrier layer, at least one dielectric, and at least one second electrode. A metal, an alloy, or a conductive oxide is used for the barrier layer.

Passive ceramic component

The invention describes a filter arrangement as well as an electronic component, each with a bulk acoustic wave resonator unit which is present on a carrier substrate ( ). A reflection element ( ) is provided between the carrier substrate ( ) and the bulk acoustic wave resonator unit for the purpose of acoustic insulation of the generated oscillations. This reflection element ( ) may consist either of several layers of alternately high and low impedance or, if the acoustically reflecting substance has a sufficiently low impedance, of a single layer. In addition, a mobile telephone device, a transmitter, a receiver, and a wireless data transmission system as well as a method of manufacturing an electronic component are described.

Bulk acoustic wave filter

A method for the fine tuning of a passive electronic component having at least a carrier substrate and at least one electrically conducting layer containing a material having a conducting nitride, a conducting oxynitride, a semiconductor, or chromium, by means of a focused laser emission, which laser emission induces a heating effect which heating effect causes the material to be converted to a locally electrically non-conducting material.

Method for the fine tuning of a passive electronic component

The invention describes a method of manufacturing an electronic thin-film component comprising at least one stripline. In this method, first a metallic base layer is deposited on a substrate layer, a photoresist layer is applied to this metallic base layer, and structured in accordance with the stripline(s) to be formed. An electroconductive layer is deposited on the exposed regions of the metallic base layer. Subsequently, the photoresist is removed and the metallic base layer is etched. This method has the advantage that less metal is required as compared to other thin-film methods. Overlapping areas of the striplines can be formed readily, economically, and with small current capacitances by means of bridges. By means of the method described herein, passive components, such as thin-film couplers for high-frequency applications or thin-film coils can be readily obtained.
