HF signal transmission line has 3 line conductors with first and second conductors and second and third conductors respectively forming 2 partial lines with capacitive coupling between first and second conductors

摘要

The HF transmission line has 3 separate conductors (1, 2, 3) extending between its input (I) and its output (O), the input ends (10, 30) of the first and third conductor forming the transmission line input and the output ends (21, 31) of the second and third conductor forming the output of the transmission line, with a capacitive coupling between the first and second conductors. The first conductor and the second conductor form a first partial line (L1) and the second conductor and the third conductor form a second partial line (L2) with a higher characteristic impedance and/or a lower damping value.
