1. A tunable differential transmission line segment, comprising:
a differential pair of signal line segments arranged in a first plane; and
a pair of tuning line segments arranged in a second plane substantially parallel to the first plane, wherein
the pair of tuning line segments is at least capacitively coupled to the differential pair of signal line segments,
the pair of tuning line segments is connected with its respective end terminals to a common reference potential, and
the tunable differential transmission line segment further comprises a tunable element arranged between a first portion and a second portion of the pair of tuning line segments.
