    Abstract: An electrical multi-layer component includes a body having a stack of ceramic layers, with a top and a bottom. First and second connection surfaces are on the bottom of the body. Electrode surfaces are in metallization layers among the ceramic layers. Via contacts are between metallization layers. At least one of the via contacts is connected electrically to an electrode surface or to a connection surface. An electrode surface connected to one of the connection surfaces, through a corresponding via contact, is a first electrode structure or a second electrode structure. At least one of the first or second electrode structures includes a via contact that has a blind end. A shortest distance between the first and second electrode structures is a vertical distance from the blind end to: (i) a metallization layer above or below the blind end, or (ii) a blind end of another electrode structure.

    Abstract: A functional block of a front-end circuit for a communication device, which is employed for multi-band and/or multi-mode operation, is proposed. By positioning, according to this invention, a pin diode switch in one of the parallel signal paths instead of positioning it on the input side before separating the signal paths, it is possible to do without an impedance transformation network on the input side and to thus reduce the signal loss and the space requirement of the circuit. In a further configuration, the signal paths preferably associated with the adjacent frequency bands are combined on the output side, whereby the further processing of the signals corresponding to the different frequency bands takes place in one path. This for example allows a chip set designed for (n−1) frequency bands to be used in a transmission system designed for n bands. Another embodiment of this invention enables monitoring of the received signal of a system even during operation of the other mode in a multi-mode system. Stable electrical properties of the circuit can be achieved according to this invention through integration of all components of the front-end circuit in one module.

    Abstract: A stripline filter includes a ceramic substrate having first and second mutually opposite side surfaces and an end surface. At least one stripline resonator is disposed on the first side surface. Capacitive coupling structures are disposed at the end surface for coupling a high-frequency signal in and out. Ground metallizing covers the ceramic substrate except for the first side surface and the end surface. The coupling structures are formed by coupling metal surfaces being disposed on the second side surface and a galvanic separation being disposed on the second side surface and separating the coupling metal surfaces from the ground metallizing; metal surfaces being disposed on the first side surface and being galvanically separated from the stripline resonators; and through holes being formed in the ceramic substrate for galvanically connecting the coupling metal surfaces and the metal surfaces to one another through the through holes.

    Abstract: A module for a mobile radio device is proposed, whose central element is a multiswitch MS, which, as desired, can connect outputs for transmission and/or reception branches SZ, EZ of different mobile radio systems to an antenna ANT. The module is suitable for a multiband operation and, optionally, additional multimode operations and includes at least one pair of outputs for transmission and reception branches of a frequency duplexed mobile radio system. Between each output of the multiswitch and the antenna, a matching element is provided, which allows an electrical matching of the branches to be connected to it. The duplex operation is carried out via separate transmission and reception filters, or on the switch via separate outputs for transmission and reception branches.
