RF COMPONENT WITH REDUCED COUPLING AND SUITABLE FOR MINIATURISATION

摘要

The invention relates to an RF component C with reduced electromagnetic internal coupling and therefore being suitable for miniaturisation. The invention also relates to a method for producing a component of this type. The component C comprises a ladder-type micro-acoustic filter in a housing H and a double coil DCL having a first coil segment S₁ and a second coil segment S₂. The two coil segments S₁, S₂ are oriented in opposite directions. The two coil segments are arranged in one position without cross-over and the double coil DCL is arranged in proximity to a parallel-branch resonator of the ladder-type filter structure.
