Claim:
1. An electronic circuit comprising: a semiconductor chip with a single-ended I/F including a signal pad via which single-ended signals are exchanged and a grounding pad, the signal pad and grounding pad located on a bottom surface of the semiconductor chip; a mounting unit having a top surface with (a) a differential transmission path comprised of a plurality of coplanar strip track conductors formed on the top surface for transmitting a differential signal and (b) a coplanar branch strip track conductor, the semiconductor chip being mounted on the top surface of the mounting unit so that the signal pad of the single-ended I/F is facing the mounting unit and is directly electrically connected to one of the strip track conductors, the signal pad overlying a pad that terminates the one strip track conductor, the direct electrical connection being made via the signal pad and the pad that terminates the one strip track conductor, and a thin film grounding layer disposed on a bottom surface of the mounting unit that faces away from the top surface of the mounting unit, wherein:
