    摘要: A transmitter module for mobile radio applications includes a multilayer module substrate with levels of metallization and intervening dielectric stacks in which a circuit is implemented by structuring the levels of metallization. In or on the module substrate, at least one HF filter or adjustment network is implemented. On the underside of the module substrate, a cutout, in which a chip element is soldered in a flip-chip-arrangement, is provided. The rear of the chip element pointing to the outside displays a metallization that makes a good thermal contact of the chip element with extrinsic circuit surroundings possible.

    摘要: A transmitter module of a wireless transmission system with at least one transmission path having a power amplifier disposed at the input side includes a low-pass filter disposed at the output side and an impedance converter disposed therebetween. The power amplifier and the low-pass filter are, thereby, disposed on the top surface of a multi-layer carrier substrate. Preferably, the impedance converter is disposed in metallization planes of the carrier substrate. The inventive integration of all of these components in one module especially allows for a step-wise impedance adaptation between the low-impedance amplifier output and the output of the transmitter module having a defined output impedance (e.g. 50 ohm), whereby the impedance adaptation is partially carried out by the low-pass filter. A multistage impedance adaptation allows for a reduction of, e.g., the length of the line sections used in the impedance converter and the signal losses involved.

    摘要: The invention relates to a capacitor with two or more opposing pairs of electrode layers (1) with an intermediate dielectric layer (2), in which the dielectric layers (2) comprise a ceramic material that contains at least two different components existing in separate phases, in which each component exhibits a perovskite structure that contains silver in the A-positions and niobium and tantalum in the B-positions, and in which the composition of a component A and the composition of a component B are each chosen in such a way that TkεA and TkεB exhibit different signs within a temperature range. The suitable mixing ratio of the components can, for example, be realized by stacking green compacts of component A on green compacts of component B in a suitable quantity.

    摘要: The formation of a two-dimensional color pattern (9) consisting of colored pattern elements (10) enables a particularly compact and faultproof color pattern for a coding to be provided. The aim of the invention is to determine the projection angle PHI for a pattern element in the picture record of the two-dimensional color pattern projected onto an object. Three dimensional data of an object point can be calculated by subsequent triangulation at a known position of the projector and a camera.
