Abstract:
A front end module has two signal paths for operation in two different frequency ranges which can be operated both with one antenna in the multiplex operating mode and with two antennas in a second operating mode. The respective operating mode is actuated via corresponding contact being made with the module substrate, and therefore by the user.
Abstract:
According to one variant, an electrical component is specified, with a substrate (1), through which a heat sink (109) that is integrated into a filter realized in substrate (1) is led. According to a second variant, an electrical component is specified, with a substrate (1), through which a heat sink (103, 104) that serves to conduct signals is led. According to a third variant, an electrical component is specified, with a substrate (1), through which a heat sink (105, 108) that is connected to a conductive surface (111, 112, 113) buried in substrate (1) is led.

Abstract:
An electrical component that includes a substrate that includes at least one electrical circuit is described herein. The electrical component also includes a heat sink in an aperture through the substrate.
Abstract:
A ceramic multilayer construction includes three resonators designed as parallel strip lines that are capacitatively or magnetically coupled to each other. All circuit components are implemented in the form of metallizations in multilayer construction. Capacitative couplings are implemented by coupling capacitors. The strip line resonators are shortened by shunt arms to ground having grounding capacitors arranged therein.
