Electrical Component

摘要

An electrical component, e.g., a diplexer or a duplexer, can have one of a number of diverse arrangements for terminal surfaces on the substrate bottom. For example, the terminal surfaces for first and second filters are not disposed at the maximum distance from one another. First and second filters can be disposed as one or two discrete components on the substrate, wherein one filter can be implemented as being integrated in a multilayer substrate.

主权项

1. An electrical component comprising:
a substrate having a rectangular bottom surface; a first filter implemented in or mounted on the substrate; a second filter implemented in or mounted on the substrate; a common signal connection, both the first and second filters being connected in parallel to the common signal connection; a first filter connection at the first filter; a second filter connection at the second filter, wherein the common signal connection and the first and second filter connections are disposed on the bottom surface of the substrate and are each assigned an individual terminal surface carrying a signal, or a pair of terminal surfaces balanced to each other with respect to ground, thereby implementing respective component connections; and a plurality of ground terminal surfaces disposed on the bottom surface of the substrate; wherein altogether at least seven terminal surfaces are disposed near edges of the rectangular substrate; and wherein at least one of the ground terminal surfaces is disposed in a corner of the substrate bottom and is further away from a terminal surface of the signal connection than a terminal surface of the filter connections, wherein at least one filter connection comprises a pair of terminal surfaces balanced to each other with respect to ground, that are at different distances from the signal connection and are disposed on the substrate bottom, and wherein the terminal surface of the pair that is disposed closer to the signal connection comprises a smaller surface area than the respectively other terminal surface of the pair.
