Integrated circuit for generating or processing a radio frequency signal

摘要

An integrated circuit includes a signal line for carrying a radio frequency signal; a coupling line inductively coupled to the signal line for delivering an induced signal in dependence on the radio frequency signal; a connecting line connected to a pick-off point of the coupling line for picking off the induced signal from the coupling line; and a conductive part for shielding the coupling line against electromagnetic interference and for enhancing inductive coupling between the signal line and the coupling line. The conductive part may have a uniform flat surface facing the coupling line. The signal line may extend parallel to the surface. The coupling line may extend parallel to the signal line and may be arranged between the surface and the signal line.
