Abstract: An RF component can have a reduced electromagnetic internal coupling and may be suitable for miniaturization as a result. The component includes a micro acoustic filter of ladder-type design in a housing and a double coil having a first coil segment and a second coil segment. The two coil segments are oriented in opposite directions. The two coil segments are arranged without crossover in one layer and the double coil is arranged in proximity to a parallel branch resonator of the ladder-type filter structure.

Abstract: 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.

Abstract: A circuit arrangement can be used for adapting the electroacoustic properties of an electroacoustic component. The circuit arrangement includes a first conductor loop and a further element. The first conductor loop includes a main loop and a negative feedback loop. The negative feedback loop has a sense of curvature that is opposite to a sense of curvature of the main loop. The negative feedback loop compensates for a coupling between the main loop and the further element.
