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.

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.
